Subject: [Patch 0/3] threaded mmap tweaks
Date: Thu, 23 Feb 2006 10:17:17 +0100	[thread overview]
Message-ID: <1140686238.2972.30.camel@laptopd505.fenrus.org> (raw)

Hi,

I've been looking at a micro-benchmark that basically starts a few
threads which then each allocate some memory (via mmap), use it briefly
and then free it again (munmap). During this benchmark the mmap_sem gets
contended and as a result things go less well than expected. The patches
in this series improved the benchmark by 3% on a wallclock time basis.

Greetings,
   Arjan van de Ven
