@Dan: thanks for sharing your config, with all your flags I don?t seem to get more that 3,4K IOPS and they even seem to slow me down :( This is really weird. Yes I already tried to run to simultaneous processes and only half of 3,4K for each of them. @Kasper: thanks for these results, I believe some improvement could be made in the code as well :). FYI I just tried on Ubuntu 12.04 and it looks a bit better because I?m getting iops=3783.
