I've noticed bad stuttering after some time of using uTorrent. P2P Shield is installed, but uTorrent specifically is disabled (default settings). Mouse is laggy, Youtube videos start to skip (sound mostly), however in Task Manager, there is nothing unusual in terms of CPU usage. uTorrent.exe goes to 5-9% max but that's nothing really. After i've disabled AIS firewall and enabled back WinXP firewall, it seems to work fine. No mouse lag, nothing. So, based on this, i can assume AIS is causing it. Any idea for further investigation is welcome.
AIS 5.0.418
WinXP SP3
uTorrent 2.0
