rafi Posted August 21, 2010 Report Share Posted August 21, 2010 About ~40% of the peers are now running v2.03 and above, so I tried to check and see how past uTP related issues are now tested:1. uTP PPS (packet per seconds) - the rate, mostly caused by small packets - was horribly large in 2.x (pre-2.0.3) releases http://forum.utorrent.com/viewtopic.php?id=784102. Overhead - was outrages, sometimes in the range of 15-25% http://forum.utorrent.com/viewtopic.php?id=69592For this test, I tried to conduct somewhat synthetic check - downloading a single OpenOffice torrent, not having too many seeds. This way I could filter out all IPs that do not have v2.03 and above.The end result is promising: 1. uTP has a nice flow of large packets of size 1444 bytes (resulting in low PPS) 2. Overhead is minimal (~3% in download, ~2% in upload/seeding), even a bit better than TCP.This is in no way a realistic test (no upload, not many peers, minimal connect-attempts), but shows great potential when more people will upgrade to 2.03+ So, thanks for fixing the broken issues, and listening to my bugging ...
