Subject: Poor performance with Linux 3.x as dom0
Date: Wed, 02 May 2012 15:11:39 +0200	[thread overview]
Message-ID: <4FA1328B.6070602@hfp.de> (raw)

Hello Jeremy + Konrad + all kernel devs,

while it is great to see that vanilla dom0 seems to work, the 
performance breakdown compared to xenified 2.6.34 (from opensuse) is 
huge. Here are my benchmarks:

Xen 4.1.1, Xeon E5620, Supermicro X8DTi-F, 12 GB RAM, dom0 2 VCPUs

time emerge apache:

		3.2.12-dom0	3.3.4-dom0	2.6.34.10-dom0
	real    1m0.560s	0m59.971s	0m47.689s
	user    0m40.939s	0m40.619s	0m41.355s
	sys     0m18.865s	0m18.305s	0m11.441s

time make -j4 (3.2.12 linux compile):

		3.2.12-dom0	3.3.4-dom0	2.6.34.10-dom0
	real    5m8.793s	5m4.888s	4m20.576s
	user    8m1.746s	7m59.726s	7m10.375s
	sys     1m39.010s	1m32.994s	0m56.304s

Regards Andreas
