Subject: [parisc-linux] lmbench results for A500-44 SMP
Date: Thu, 7 Oct 2004 21:18:50 -0700	[thread overview]
Message-ID: <20041008041849.GH14151@tausq.org> (raw)

First entry is for 2.4.20-pa24 SMP
Second entry is for 2.6.9-rc3-pa3 SMP, with a cache flushing patch

Machine is a 440MHz a500 with 5GB of RAM.

In general our performance seems to have dropped a bit :(
