Subject: 2.5.36-mm1 dbench 512 profiles
Date: Thu, 19 Sep 2002 15:30:07 -0700	[thread overview]
Message-ID: <20020919223007.GP28202@holomorphy.com> (raw)

Well, from some private responses, it appeared this is of more general
interest than linux-mm, so I'm reposting here.

I'll follow up with some suggested patches for addressing some of the
performance issues that may have been encountered.
