Subject: Re: [uml-devel] [PATCH] host context switch reduction Benchmarks
Date: Thu, 27 May 2004 23:53:42 -0500 [thread overview]
Message-ID: <001001c4446f$c323d2e0$0201a8c0@hawk> (raw)
In-Reply-To: 1085658646.1256.9.camel@chartreuse
Using Mysql's "run-all-tests" as a benchmark, the sysemu patches provide about a
33% performance improvement over a "vanilla" UML+skas.
w/ sysemu:
real 13m57.353s
user 2m17.370s
sys 3m54.310s
w/o sysemu:
real 18m38.329s
user 2m37.370s
sys 6m3.040s
Mysql test results here:
http://www.theshore.net/~caker/uml/sysemu-benchmarks.txt
For a kernel compile, the improvement isn't as drastic -- but compiling spends
most of it's time in user-space...
w/ sysemu:
real 5m15.182s
user 4m22.470s
sys 0m52.230s
w/o sysemu:
real 5m28.466s
user 4m32.030s
sys 0m55.370s
Nice stuff, thanks!
