I wont recommend Bitcomet anymore. It sucks now.
I was happily downloading from 50-150kB/s using the previous version.
After I format my PC, it seem to went wrong. Using 0.76 seems to crash every now n then. Download was crawling all over the places and downloads always stucked at 99.x%. Now only I get why my bro n sis grumble Bitcomet was slow when I installed them on their PC.

Now I too have moved on to Utorrent and gained back to 50-150kB/s speed. To hell with Bitcomet.
