I did a quick test with the last version on the same testbed environment that I used for my previous blog and here is my finding.
MySQL 5.4 worked as I expected with sysbench. Performance up to 32 threads are basically the same of my build, but whilst 64 concurrent threads show a degradation in performance of the standard build and my build, with 5.4 they increase significantly, showing a pretty linear scalability - see table and graph.
Threads 5.1.33-Std 5.1.33-IZ 5.4 1 28.63 31.28 28.63 2 58.15 60.21 58.57 4 93.56 108.14 96.57 8 170.46 179.59 166.93 16 286.28 307.78 271.09 32 352.90 400.14 392.68 64 307.62 366.04 576.55 128 222.49 266.61 247.96
I would not recommend to go for 5.4 yet, but the results are extremely promising.
