Lukor, do you need any extra data or you already have everything you need, you just have to write a fix for it?

Having some spikes of red in one program does not mean anything, if your system does not respond, your mouse is not smooth, your sound is choppy - that's a problem.
System is very responsive, mouse is smooth, sound is clear in Media Player 12 - so no problem for me.

Will it be fixed in avast! Free ???

Does the free version even come with the NDIS driver which is purely for the firewall?
The AV itself doesn't have an issue regarding DPC latency.

DPC Latency Checker won't tell you where the problem is either.
You need to use LatencyMon or Xperf for XP together with sysinternals procmon so that you can track down the exact code causing the issue.

Loads of 8ms + DPC latency spikes are pretty bad, saying that they don't affect anything is a lie.

Hi guys, I can confirm some DPC issues with AIS Firewall in the current version with massive connection counts. We are currently analyzing the problem and trying to come up with some fix, hopefully for the upcoming version 6.

Great news  8)

There is no firewall NDIS driver in the free version that has no firewall.

Really getting tired of this freakin bug.

Given that the last post in this topic was over two years and several versions ago, I would have liked to have though it would have been resolved by now.

That said I would say that it is probably better to start a new topic given this one is ancient and for very early versions of avast.

Are you really using AIS version 5 as in your signature ?
If so that may well be the problem as subsequent program updates will have changed the firewall module.

Signature was outdated. I only come around most times when a beta is on going or get irritated by this issue.

I've posted in others previous but as a reminder of history I pulled this one back up.

Actually there is a recent topic discussing the same problem:

Unfortunately history isn't related, whilst it is/was DCP Latency so many avast versions later and a complete change in the firewall, etc. only confuses matters. So joining a more recent topic (as zerotox gave) or starting your own would have been better/ more related.

I'd like to know how things stand about this. I was thinking of buying avast! IS, but now i'm unsure. I need it to work flawlessly because i game a lot online and i can't have any latency issues, system or network...

I don't know what change at my pc in the last days caused the dpc latency to go down again, but I'm happy
What I did in the last days (might be one of those):
Avast Update (There was a program update it might have finally fixed those issues)
Malwarebytes Anti-Malware Search (in the free version) -> deleted a few files and registry settings containing pup (there was something about the firewall and antivirus, I think the notification in the windows action center was disabled, PUM)
latest Windows updates
Updated a lot of programs to their newest version
uninstalled avast grimefighter, browser-addon and "easy access and mangement" (it might be called differently in english, it's the last point in the middle column in uninstall tool)

If there is something else I forget to write about I will edit this post

Hopefully the issue gets fixed for you now as well ;)
I'm almost sure it was the avast update
I'm usign the free Avast version btw. so there might be issues in the avast firewall still (for the pro/internet security version), you have to test it on your system, because my issues might have been related to something else since I couldn't make out the source of the issue 100%


@RejZor this has nothing to do exactly with network and system latency
it's more like the responsivity of your drivers which cause sound cracks because the PC cannot handle the sound in real-time anymore because other unrelated drivers cause latency in the system
you probably won't recognize it while playing except for the sound issues (as far as I know)
