linux-rt and 2.6.23 low performance in wine

Asked by Pawel

I've installed linux-rt kernel and now, wine applications run much slower than on linux-generic. The same issue concerns kernel 2.6.23 which I've compiled manually (no matter what configs were used - generic or rt, performance is very poor in wine).

Results using "time wine application_name" (in this case it's Homeworld Cataclysm):

linux-generic:
real 1m4.680s
user 0m21.173s
sys 0m17.853s

linux-rt or 2.6.23 (values are almost identical):
real 1m8.508s
user 0m25.805s
sys 0m28.115s

In Kubuntu 7.04 I didn't notice any diffrence in performance in wine between linux-generic and linux-lowlatency kernels. Why performance is so pure using kernels different from linux-generic in Kubuntu Gutsy?

This seems like very old question. Have you found solution to this? Have you tried latest ubuntu and wine releases?

I tried only Ubuntu 8.04 and it wasn't solved for me. I don't have 8.10 right now, so I am unable to test it. I noticed low performance in few games: Homeworld, The Temple of Elemental Evil (only movies affected). Divine Divinity in example worked excellent. It seems that I can safely mark this question as solved, because I posted bug report too and its status is - fix released. Thanks.
