Posted: Wed Oct 23, 2013 11:27 am Post subject: NIC card - CPU Overload |
|
|
Hello.
I have installed Gentoo in order to use it a router on a Dell 1950 poweredge server.
This is used for core routing,and it subject to a large number of pps (> 60000 during peak hours).
This server has 2 Quad-Core CPUs, meaning interrupts should bedistributed between all 8 cores equally.
The server had a stock Broadcom NetExtreme NIC card which did not perform well. Normally the load was around 10% on all cores, but when a lot of interrupts were generated,one the of cores hit 100% load and it was stuck for a short time while the others dropped to 0.1%. This meant that all IRQs were sent to an overloaded core and as a results, I had a lot of packet loss. Then it started balancing IRQs normally after a few minutes,and then the process started once again.
In order to solve this problem,I upgraded to an Intel I350-T2 NIC card,which reportedly uses the IGB driver for Linux and should perform better.
The problem is still present. During the day all traffic is balanced over the 8 cores, but when more IRQs are generated, one of the cores is locked for a few minutes and the others are idle. This sound like a software problem,not a hardware one. Would changing the kernel have any effect?
I am thinking of downgrading to 3.8 instead of 3.10.7.
Please let me know if I can look at any logs because dmseg and general info in /var/log/messages are not very helpful.
I have tried increasing the TX buffer (since I had TX drops,not RX). Also, would changing flow control help in any way?
Below I will post all the info I could gather.
