Hi,
Is anyone aware of major performance problems in the latest OpenVZ
kernels - I just posted a bugzilla report here with a ton of graphs:
https://bugzilla.openvz.org/show_bug.cgi?id=2556
I went from Debian 6 (excellent performance) stock kernel to Centos 6.4
(terrible with ksoftirqd bug also report -
https://bugzilla.openvz.org/show_bug.cgi?id=2554) latest VZ kernel to
Debian 6 Proxmox kernel (also contains ksoftirqd bug) - both latest VZ
kernels for CentOS and Proxmox were awful in performance - something was
eating up all the CPU in user, but top show only small CPU usage inside
the containers. Back to Debian 6 stock with a kernal circa 2011 and
performance is flying again.
I checked all the usual suspects, RAID configuration, deadline
scheduler, blockdev size - over just a major lag - perhaps people don't
notice it or perhaps it's a known problem? Does anyone else have this
experience of coming from the older Debian 6 vanilla kernel?
Keith
