Message-ID: <30855636.2.1392893933953.JavaMail.root@zimbra> Date: Thu, 20 Feb 2014 11:58:54 +0100 (CET) From: Roy Sigurd Karlsbakk <roy@...lsbakk.net> To: Linux Kernel Mailinglist <linux-kernel@...r.kernel.org> Subject: Interrupts from ethX sticking to one core Hi all I'm running a NAT44 gateway on Debian Wheezy, kernel 3.2, and timers from eth[01] sticks to cpu0 even though I've set cpu_affinity to 0f (4 cores). This is a VM on ESXi. Setting affinity to a specific core works, but the kernel doesn't balance interrupts dynamically as I would have hoped it should, even when CPU load is at 95% (mostly soft interrupts). I also tried to install irqbalance without this having any effect. Drive used is e1000 (for the moment, will move to vmxnet3, but afaics from testing on another host, this didn't solve the problem). Is this a known issue? Any way I can fix this?
