Tweaks to increase bitcomet download speed:

1.Hack the max TCP connections on Windows XP

If you are currently using on Windows XP sp2, your Windows TCP connections are limited to a maximum of 10. I highly recommend your modify Windows TCP/IP.sys with LvlLords Event ID 4226 Patcher to get better performance bittorrent download speed. If not modifying Windows TCP/IP.sys, It will seriously hurts your BitComet download speed because it wont let you connect to a high amount of ip numbers.

2. BitComet Connection Preferences

Click – > Option – > Preferences ( CRTL + P)

When you see the connection properties. There is no Limit on “Global Max Upload Rate” or “Global Max Download Rate”. I’m highly recommended you lets your upload rate to 90% of overall upload and download speed. At least, you still have overall 10 percent to surf internet or downloading other internet files.

For Task Schedule, It’s an useful bitcomet tweak option. As you see, Max Simultaneous download task is 10 but if you have fast internet connection and plan to downloading more torrent files. You can setup the number of download task higher. Listen Port also important on bitcomet tweak. As some of country ISP’s have blocked the default Bittorrent ports, So, you can choose or enter specific port number to listen on. For improve the downloading, if you set your internet modem port forwarding features to your computer IP address.
