In many cases I see 200 peers are not enough
I have 15 mbps connection but I get only 900-1000kbps when downloading but it should be 1.8mbps because of this (Pic Removed by Mod)

Tixati only allows me to connect to only 200 peers I cant raise it more than that. How can I? Please help

The problem is not so much how many peers you are connected to, rather the quality of the peers, I find the ideal quality of peers is around 12, Having hundreds of peers connected keeps your computer busy lessening your overall download speed while having less peers will speed up your overall download rate. I find it normal that my download rate is over 1,000 kp/s with less than 12 peers. Ignore or IP ban all the scrubs who upload at less than 5 kb/s and see the difference.

Or you could ban by country, basically all countries except Russia, Korea, Sweden, Denmark, Hong Kong, Ukraine, Malaysia, Singapore, a few other Eastern European countries.
