I've been doing some benchmarking of the 2.2pre kernels and various patches in
development. I am looking for memory management benchmark utilities. Something
like Bonnie for vm subsystem benchmarking. I'm concerned about the
comprehensiveness of my own simple tests. What I'm finding is that while 2.2 is
outperforming 2.0.36 in some situations, it is falling far behind in others.
Particularly the very low memory case (6M with X running) 2.0.36 performs far
better (Even though the overall 'available memory' as reported by top is
actually slightly *greater* for 2.2. Andrea Arcangeli's recent patches have
improved things a great deal but I still haven't found anything to beat 2.0.36
in very low memory. It would help to have a suite that gives a more
comprehensive view of mm performance.
Also, no matter how good the suite is, it will only tell me about the
performance of my particular hardware layout. The more people who test and
submit results, the better 2.2/2.3 mm will be.
Thank you for any pointers,
Steve
