Oracle recently announcent MySQL-5.5.2-m2 milestone, and I have a predition that MySQL-5.5 will be announced as GA on MySQL UC 2010 in April.
So let’s make quick on scalability characteristics we should expect from new release.
I made sysbench oltp benchmarks on 10 mln rows (worth 2.5GB of data), on our Dell R900 system ( 16 cores, 32GB of RAM, FusionIO + RAID10, but disk in this case does not matter).
There is results for various threads (results are in tps, more is better)
I think it is good results, and there couple conclusions we can come with
If you interested what is issue in scaling over 16 threads, that in current
benchmarks – this is concurrency on rollback segment (which is global shared structure in InnoDB)
sysbench command for reference:
./sysbench --test=oltp --oltp-table-size=10000000 --init-rng=1 --num-threads=$i --max-requests=0 --oltp-dist-type=uniform --max-time=180 run
