Andre,
Please see the related thread on this list, "High CPU usage / load
average after upgrading to Ubuntu 12.04". You may be experiencing some
of the same issues. General perspective seems to be that kernels 3.0
through 3.4 have serious performance issues.
Josh,
I saw that thread, but it did not appear to be the same symptoms that I had.
Where they have a high load average, I only saw spikes during which the server
was unresponsive. During that time the load would jump to 50-70 (on 24 cores).
Anyway, after upgrading the Kernel to 3.4.28 and the latest Intel network card
driver the problem seems to be gone.
