Lots of people are having trouble uploading & downloading and bitcomet don't seem to care. They ignore all requests for help and just tell people they are being throttled by their isp. This is a long post but PLEASE read! It's worth it!
I got so fed up I removed bitcomet and started using Utorrent, mostly because I couldn't upload. Now my upload speed is back to normal, so it was always a problem with bittorrent, not my isp. The download speed is quite slow but that just means you can have finished uploading to 2.0 by the time you've finished downloading.
A long time torrent experet said I should try downloading with bitcomet and uploading with Utorrent. I tried this, after using only Utorrent for about a week. Suddenly my download speeds with bitcomet were good again (coincidence?)
I reccommend using Utorrent ONLY for a week or so, then uploading with Utorrent and downloading with bitcomet (only using one program at a time of course!) I download with bitcomet at night (when I get the best speeds) and upload during the day. because Utorrent uses much less system resources, I have been able to use my computer for work all day and upload (at unlimited speeds) on the same machine with no problems.
Everybody who is having problems please try this! If we all leave bitcomet, they might actually fix it! If you go to a page of new torrents, like Torrentz or Mininova, you will see new torrents, even ones by popular uploaders like axxo have almost no seeds. I believe this is because people are having the same problems uploading with bitcomet. Bitcomet seem to be happy for the torrent community to die rather than fix this problem. Please keep the torrent community alive by using Utorrent!
