With a lot of talks around 5.4 I decided to check how it works in our benchmarks. For first shoot I took tpcc-like IO-bound benchmark (100W, ~10GB of data, 3GB buffer_pool) and tested it on our Dell PowerEdge R900 box (16 cores, 32GB of RAM, RAID 10 on 8 SAS 2.5″ 15K RPM disks). For comparison I took XtraDB-release5 and 5.0.77-highperf percona release.
For raw results you can check my Google Spreadsheet (it is also being update with my next CPU benchmarks, and benchmark on SSD & FusionIO), also I post graph there:
Results are in TPM (transactions per minute, more is better).
So I can confirm that MySQL team did great job with 5.4 and it shows the best results.
Some more results you can find on Dimitri’s blog, one of Sun Performance Engineers.
From our side we will look on recent improvements and also on Google V3 patches and will integrate them into next release of XtraDB, so stay tuned
