[OpenAFS] Backups CPU-bound... any way to speed up?
Mon, 29 Sep 2008 12:29:08 +0300 (EEST)
I've noticed that my backups of AFS are throttled by the CPU.
(I'm backing up to intermediate disk files and from there to tape
using NetWorker. Both volserver and vos are rather hungry for CPU,
I notice. I have disk systems that could take a lot more than is
currently being fed from/to them, but the speed of my backups is
being limited by the CPU resources available.)
I'm still on commercial AFS. Replacing volserver and vos with the
OpenAFS 1.4.7 versions only made the matter worse. Any insight
(or better yet, help that does not rely on replacing the hardware :-)
would be welcome.
