If you ever p2p you'll know that pretty soon your going to get timeouts (especially on BT networks), previously I used
NetLimiter to control the bandwidth on the p2p Application i used (back then it was
Azureus - Memory hogging Java app!), however it was ineffective at times, still throttling my connection and causing me timeouts.
A few months later I switched to this brilliant tool called
cFosSpeed. cFos installs a low-level driver that actually allows you to prioritise (or load balance) application's bandwidth. So for instance all standard internet traffic gets high priority (Eg. Web Browsers), where as p2p clients can be given "LOW" and it will manage the connections efficiently. I have to admit that I was pretty adamant at first, but after using it for little over than 3 months now I'm more than impressed. I rarely use "Optimisers" or such tools (like the world of bloated 'RAM Optimizers' out there that dont really do anything useful!) but
cFosSpeedis something totally different.
So if you're an avid p2p'er(legal or otherwise) download an evaluation and take a look, they've got a special 9€ price on it till the 31st of January so its even better!
