[Xen-users] Transient xen performance issue



I'm installing Xen with the OpenSUSE 10.2 distro and the bigsmp-2.6.18.8-0.13.i586 kernel. However, I occasionally get insane amounts of slowdown (almost 100x) in dom0. On bootup, performance is normal. After an undeterministic period of time, I get this crazy amount of slowdown. I'm not sure why this is the case and I have spent a long time trying to figure it out. There are no background processes running and nothing CPU intensive shows up on top or ps aux.

One point of interest is that when I run 'lsmod', the modules ide_core and ide_disk are missing. I tried installing them but it seems that they aren't necessary. Since performance is fine on startup, I'm not sure if this is a problem.

I'm installing and compiling Xen 3.3.0 from scratch by using "make world", etc.

Does anyone have any ideas or suggestions?

Thanks!

Dan
