Thanks for reply, however it seems I'm not the only one -

BTW, some more details about my IO hardware: the server uses hardware
RAID-10 with BBU. Initially Percona was running using O_DIRECT for
InnoDB flushing but then I switched to the default flushing mode and
IO numbers became somewhat better... However after this I got several
data corruptions and simply stopped any further experiments.

Best regards, Pavel
