Avast Free Antivirus / Premium Security

Just to let you know, i’m still getting awful stuttering and lagging of mouse cursor when AIS firewall is enabled and i’m downloading through uTorrent. No P2P Shield used…

hmmm, are you familiar with DPC Latency Checker?

could you please check DPC Latency during uTorrent and post a screenshot here?
we’re mainly interested in red bars (e.g. http://www.thesycon.de/dpclat/dpclat2.jpg)

thanks

I’d say it goes through the roof. Though i’ll test that tommorow evening because its late now and it takes a bit of a time for this issue to happen. And i just happen to have a longer work day tommorow grrrr…

Hi RejZoR,
I’ve sent you a PM with some instructions if you are up to for some experimenting :stuck_out_tongue: Thanks. Lukas.

Any more details on this?

Definitely a DPC latency issue here. As soon as I start AIS FW, DPC shoots to steady 16000us+ if utorrent is downloading and goes back to “normal” as soon as I kill FW (just using the start/stop FW setting in Avast is enough).

Requirement is that utorrent + FW has been running for some time (the problem doesn’t kick in immediately, even if utorrent is running at full speed → something goes to “spinlock” state in FW only after some time).

AIS build 1203, Win7 x64 Home, AMD X2 4400+, 4GB.
