Poor speed after updating debian squeeze to wheezy

[Lazybones]

My Deluge download performance seems to have tanked after doing a distro upgrade.

under squeeze I had installed 1.33 from source and was running libtorrent 0.14.xxx, now as part of the distro upgrade I have libtorrent 0.15.9.0 and performance is horrible on all torrents.

I am still using my from source install, should I kill it and install from apt since I now have access to more up to date packages or is the something more simple that I may have over looked?

Was trying to search the forum for anything regarding standard things to check for speed but speed it too common of a word and performance came up with nothing.

My inbound port passes the port test still so that is covered.

Hmm looks like the slow down is limited to particular trackers, does the peer ID deluge sends appear different dependent on libtorrent?
