Gelb: Tried using the log tool? If you got the same problem as me with bittorrent, it's related to the very low buffers, catohagen's options should fix it. Didn't notice any enormous CPU loads yet. Resolving hostnames taking lots of time is due to weird config in resolv.conf, just comment away the lines and it will be normal.
Personally I didn't expect anything at all, and the current state is something that has many faults but is definitely usable. That's worth something even if, after re-reading the bounty specs, I agree that it is not finished. But I'm not sure how much sense it makes to try and finish this project as stated in the bounty specs.
