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?
