[uml-devel] 2.6.9 slow

[uml-devel] 2.6.9 slow

[Hegedus Gabor]

Hi!

I tested 2.6.9 with patched with host-skas3-2.6.9-v7.patch. It is very
slow, but there is not a big load, nor a big disk io. (I checkd with
iostat)

With 2.6.7 it is good.

bye

With SKAS or vanilla? I assume it's vanilla - might you try that with SKAS?

Well, basically SKAS is unlikely to cause that... I'd rather think that in 
your config 2.6.9 is slower than 2.6.7. Check if you've changed anything 
relevant on the kernel config.

To make sure that SKAS is not at fault:

- if it becomes slow after running some UMLs, then SKAS is probably at fault. 
Not otherwise.

- also, I guess that you'll have the performance hit even without SKAS patch 
applied. Make sure not to change the kernel configuration!
