100% CPU after built on Wed Aug 12 08:40:28 EDT 2009 snapshot
-
Yep, that what is was. I am not sure if it was enabled by default since I don't mess around with those settings too much. Also not sure why it was different from the previous snapshot. Something new with idlepoll?
Thanks for the help.

Nothing new. It's just a means of reducing CPU usage if the NIC proves to be overloading the system with interrupts. Try disabling Polling from System -> Advanced -> Miscelaneous -> Device Polling. Uncheck the Checkbox to disable device polling.

I did that. Before I disabled them it was working fine. No hardware changes and then it started doing that so I disabled the device polling which fixed the 100% cpu problem.

Hi,
i just updated to last snapshot (1.2.3-RC3 built on Mon Sep 14 01:31:26 UTC 2009) and now IDLEPOLL take make CPU to 100%. Before I've always used polling on nics and no problems. I've not changed anything on my hw.
Any idea to resolve? instead of disabling polling?Thanks for help!

Is it possible that polling, while checked, never actually worked and started working in more recent builds?
-
I don't think so…
Anyone could confim this? -
As far as I've been able to tell, IDLEPOLL is just that, idle polling.
It always shows 100% CPU because it's technically doing polling during the idle time. Any time I've used polling I have seen this behavior.
Unfortunately it makes the CPU usage meter a tad useless, but I'm not sure there is a way around it.
-
I've never seen CPU at 100%
So I've never used polling? -
I've never seen CPU at 100%
So I've never used polling?Did you turn it on?
Polling is off by default and is not needed in most places. You really only need polling if your system is passing more packets than it can handle interrupts for, which unless you have really, really old hardware, is unlikely in most places with moderate bandwidth/throughput. And even then, if it's that old, it probably doesn't support polling properly.
In places I've tested polling it's performed the same or slightly worse than without polling, but that will vary from one hardware setup to another, and depends largely on your workload.
-
I've always (from years ago) enabled polling, but now I think that never worked, becouse I've never seen CPU to 100%. I think that I don't need it, so I disabled it.
-
so does this mean its OK to have 100% cpu usage with polling?
-
I think so…
-
it seems to be working fine….just seems odd.
