Everyone,
I am running with the following configuration
2.4.19pre8aa2+dj2+ (dj2 removes global semaphore_lock spinlock)
+fast_walkA3-2_4_19-pre8_patch.
The database is set up to use raw-io, yet looking at this data, it appears that
I am still hitting a lot of filesystem accesses, among other things. This is an
oltp workload, although there are some contentions (pread?) that cause the
cpu sys time to go to 99%, it was during this part of the "workload" that this
snapshot of lockmeter was taken.
Any comments? Recommendations for other patches?
Thanks,
Ruth Forester

Dave Hanson has a do_exit patch you might want to look at...

I thought that the DB workload was running the LSE patches too. I
have a simple fix for do_exit(). This 2.4.17 patch should apply
against your 2.4.19pre8aa2+dj2... If it doesn't, I can regenerate it
pretty quickly.
