μTorrent v2.0 to add ‘game changing’ μTP protocol
Earlier this month, BitTorrent, the company behind the popular torrent clients μTorrent and BitTorrent posted that they were getting ready to “change the game” with the introduction of a new protocol dubbed μTP (micro-Transport Protocol).
The protocol will be available with the launch of uTorrent 2.0 and BitTorrent 7.0.
Says the post:
“The fact is that our BitTorrent clients have become incredibly popular with users downloading large files over the internet. So much so that some observers claim that BitTorrent traffic accounts for 30%, 50%, or even more of all Internet traffic. Regardless of the actual numbers (which we have no way of knowing), it is clear that the popularity of BitTorrent is putting such a burden on ISP networks that they sometimes react by slowing down or interfering with that traffic.
Now there is a whole “net neutrality” debate, partly about whether ISPs should be allowed to interfere with internet traffic from one particular app simply because it is “too popular” – some argue that perhaps ISPs could invest more so that supply meets demand – but this debate is not the focus here. At BitTorrent we like to be a bit more pragmatic, to assert that there is responsibility on the part of both the ISPs and authors of popular applications like BitTorrent to make sure that the internet scales smoothly to meet demand.
Which brings us back to μTP:
News of μTP started to leak to the public late last year with some wild and totally untrue reporting that we were trying to make BitTorrent more greedy and were somehow “declaring war” on users of other applications. In fact completely the opposite is true, as was subsequently acknowledged by the initial author’s follow-up article.
μTP is a completely new implementation of the BitTorrent protocol with a major new design objective – μTP is designed to be network friendly – to not swamp network connections when there are other apps trying to send and receive – and to resolve the key problem that ISPs use to justify interference with BitTorrent traffic.
If BitTorrent traffic volume is so great that it overwhelms end-users’ connections (leading to service calls from consumers whose internet doesn’t work), then μTP eliminates this problem by being better at only using bandwidth when there is no other traffic competing, and automatically slowing or stopping BitTorrent transfers before network connections seize up.
Legacy BitTorrent traffic uses the standard internet “TCP” protocol to govern when it tries to go faster or slow down. The problem with TCP is that it can only detect a problem by waiting to see if packets are dropped. Unfortunately, by the time packets are being lost, the problem is already acute and the consumers connection has already drastically slowed or stopped. TCP is a lot like trying to drive with your eyes closed. You only notice something’s wrong when you hit something.
μTP is like driving with your eyes *open* – μTP is able to see problems coming and make much more modest adjustments to ensure the problems don’t cause a car wreck. It does this by being able to detect congestion on a network based on how long a packet takes to be sent from one peer to the next. If things start to take longer, then μTP adjusts the rate of sending accordingly.
As it happens, this trick has required some very deep engineering work – the way the client talks to other clients has had to be completely re-built. As a side effect, because the new protocol so different, it is practically invisible to some of the nasty traffic shaping techniques that some ISPs have been using. We doubt whether this happy result will last for long, and nor is it the point of the technology. The point is to reduce the need for such gear rather than to evade it.
Overall, when we get μTP stable, we’re excited about the potential benefits that this could bring to ISPs by reducing the effective burdens on their networks. Although we stand to gain nothing financially from them for implementing it, we hope to maintain the lead enjoyed by μTorrent and BitTorrent Mainline software as the most popular BitTorrent clients, and hopefully demonstrate how innovation from responsible stakeholders on a neutral internet can lead to winning outcomes all-around.”

Efficient Vista Registry is Really Important to Make your Pc Run More Smoothly
A Vista registry is nothing but a centrally protected depository, which is needed by the Windows system. The application inimitably describes specific system installation, which also includes system security policy, installed applications and user-specific operating environments. This database gives us information on all installed hardware components and associated configuration information including the version number of each installed system module, and information that is exclusive to certain add-on applications. For each user who has logged on to the system interactively, the Vista Registry contains a complete description of the graphical desktop and network connections for him.
The Vista Registry is occupied by numerous system modules, which start at boot time and are added to or modified by the configuration tools accessed via the Control Panel, User Manager, NT Setup, other administrative utilities, software installation procedures and third-party configuration disks. There are occasions where one has to manually edit the Vista Registry even though NT has many graphical applets that automatically record configuration information in the Vista Registry. One can modify the information directly through the Registry Editor. A registry editor is a special editor that works with the format and layout of the configuration database.
A misstep could cause severe problems with the Operating system if any changes are made to the Vista registry. Hence, one should seek a back up of all the files before one does anything with the registry. Navigation, editing or adding a new file to the registry is very easy and user friendly. One just needs to be clear about the performance of the task. In case of a bad registry change, one can recover the system by backing up the files again and clicking ‘next’. However, this time one needs to choose ‘Restore Files and Settings’. One should click the plus sign next to File in the left panel, then again next to the backup file that one has made. Place a checkbox next to System State. Click Next, Finish, and then OK. After the restoration, click ‘Close’ and then say ‘Yes’ to restart the PC. A restoration using Backup won’t erase new keys; however it will change pre-existing keys back to their previous data.

The Unmatched Windows Xp Broadband – Cable Tweaks Guide
Does your connection crawl? I bet it does buddy, just try these few simple tweaks, lets get you fixed today. The following tweaks and modifications are the ones I personally perform to my Cable connection after fresh installing windows.
Note-This Guide works with DSL and Cable Connections!
The first thing I like to do is run over to Control Panel > Network Connections and “right click” Local Area Connection (Your primary connection)
Then I Uncheck:
“Client for Microsoft Networks”
“File and Printer Sharing For Microsoft Networks”
“QoS Packet Scheduler”
Then I like to install LVLLORD’S TCP PATCH…. (Read more info below)
Microsoft Limited TCP connections in SP2 to 10! Regain lost speed by applying lvllord’s patch. Just download the patcher and execute it. It will automatically find the windows directory and ask, if it should increase/decrease. Enter C and change the value to 100, and confirm your changes. After a successful patch, the new TCPIP.SYS will be automatically installed. Restart your computer
After I get my Tcp nicely patched, I move on and Tweak my windows xp registry settings to unleash my cable connection’s real potential. Don’t be worried if I said “I tweak my registry”, You wont have to manually edit it because I use a great free tool called Cablenut!
So you downloaded CableNut? Good! Now you are ready to start getting information to use with the program.
The first value that you will need to calculate is the Maximum Anticipated Latency of your connection. To do this, you will use the trace route command built into Windows XP. Follow these steps to get the latency value to use for your connection Alrighty so now lets find our Maximum Anticipated Latency! To do this, Download a really big file such as the .NET SDK framework at http://www.microsoft.com/downloads
While this file is downloading, run over and open up Command Prompt by opening “RUN” and typing in cmd. This brings up a nice big black window. Now you need to run what is called Tracert 5 times in this box and write down the highest number you get with every tracert.
So lets get this straight you need to run tracert 5 times each time to a different site. For example
tracert google.com
When you run it let it finish…can take up to 3mins then copy down the highest number. Do this five times, then DROP THE HIGHEST AND LOWEST VALUE and average the other 3 (add them all up then divide by 3).
To calculate RWIN use the following:
(Maximum Bandwidth * Maximum Anticipated Latency) / 8
Example of my results with a 3000 download cap with an Anticipated Latency of 100 ms:
(3000 x 100) / 8 = 37500 To make it a multiple of MSS divide by 1460:
37500 / 1460 = 25.68 Then round to the nearest even whole number:
26 x 1460 = 37960 is my “perfect” RWIN
NOW WAIT DONT LOSE THAT Maximum anticipated latency value hold on to it……lets tweak the rest of our settings (This part is quick, we finally use cablenut) enter Maximum anticipated latency value along with your connections download and upload caps in kilobits per second (kbps)into a great online CableNut settings calculator. Open up your Web browser and visit www.j79zlr.com/cablenutXP2k.php, then follow the steps to get the values to enter into CableNut:
**TO DETERMINE THE Maximum Connection Speed simply go to your Internet service provider’s website and look for it. Or you could simply email them and ask them**
After you get all those settings, change the values GlobalMaxTcpWindowSize & TcpWindowSize. to the ones you found previosuly (your perfect RWIN).
Faster Downloads
I highly recommend that you use a download manager. It allows you to resume broken downloads, choose the fastest servers for your location for optimal d/l speed and schedule your downloads. Star Downloader is my top choice.
Fastest Windows XP Browser
I am a speed freak I must admit! And when I tell you I’ve tried EVERY BROWSER…..ive tried EVERY browser! The two browsers below I currently have installed on my PC and use them both! They both rock!
Firefox (My TOP Pick)- Firefox has spread the Net faster than AIDS =) and is now an essential icon on virtually every Computer around. Even though it had a rough start I am recommending it due to its frequent updates and its ability to be tweaked. I must admit, Firefox by default is NOT the fastest browser that is until it gets TWEAKED! Be sure to download your copy of Firefox along with Firetune.
Opera – Offer Insane speed, stability and security. It has an INCREDIBLE amount of features and fun stuff. www.Opera.com
Although its said that OPERA is the Fastest Browser available, I personally think that Firefox %2B Firetune whoops Operas butt! 
Don’t let you PC slow to a crawl visit my site for more Windows XP Tweaks that will have your PC running on steroids!

Slow Startup With Windows XP – How Can I Fix The Problem?
We install programs and visit all kinds of websites everyday. Our system files fragment themselves and we tend to forget to do a regular troubleshoot scan. With all these going on, it wouldn’t be much of a surprise if you encounter a slow startup with your Windows XP. Once you notice that it takes more than five minutes for your computer to start running, there may be a problem with your computer system. A slow startup with Windows XP can be solved instantly though, and through these solutions you’ll have it running again in no time.
The first thing you should consider is that you system undergoes all kinds of processes. You install all kinds of new programs, not knowing that there are actually other small applications that are installed as well. These usually come in the form of extra applications from publishers that go with your new program or toolbars and other stuff that installs itself instantly or when you forget to uncheck the radio button. This can cause a slow startup for your Windows XP, minor as the issue may sound, so you should either try to do a disk cleanup by clicking on the Disk Cleanup tool or manually browse through your program list and uninstall those that are just sitting there unused and forgotten about.
Another solution you could try is by defragmenting your file system. Files get fragmented into clusters all the time, making it difficult for your computer to scan and function well. Though it may take some time to finish, your system may start running faster than before after defragmenting it. You can also try exiting autostart programs and disconnecting unused network connections to improve your slow computer. Autostart programs are usually activated upon startup of your computer and can eat up a lot of CPU space. Try browsing through your Task Manager, look for programs that you don’t need to use, and end their processes. That way, more disk space will be freed and the system can run a little faster than before. Disconnecting unused network connections with other computers can also help. Usually if your network connection is shared with one or more computers, the performance level of your computer goes down. If you don’t see the need to read and write files into other people’s computers, you can shut these down to get rid of a slow startup with your Windows XP.
If none of these solutions seem to work, then you may have to troubleshoot your system for a virus attack, which is one of the most significant reasons why your system is slowing down. After scanning, try restarting your computer and see how long it would take for the system to finish. This is a good way in knowing if any changes have been made. You may have to backup your files first in case you have to reformat or perform serious action with your computer. To backup your files is not overreacting; anything can happen now that new and improved viruses are spreading all over the Internet. A slow startup with Windows XP could result to a lot of difficulties, so make sure to check once in a while.
