Message #00364
some performance results from percona builds
These are sysbench readonly results from a 16 core server. I used my
--oltp-secondary-index patch. The workload is CPU bound. The numbers
are transactions/second for 1, 2, 4, 8, 16, 32 and 64 concurrent
threads. With my sysbench patch, 2X more work is done per transaction
so the results should be ~1/2 of what you get. tcmalloc helps the
binaries in which other SMP problems have been fixed. I have not
debugged the slowdowns for the other cases. Postgres thrashes for 64
concurrent users, so I don't include that result.
