Two things slows down HDD's: write() and fsync() on each message. So, I disabled fsync() and didn't get any appreciable benefits. So, the write() is the thing. If moving all queues to RAID0 won't help, I'll change postfix a bit for moving only "incoming" queue to RAM disk. "Vanilla" postfix does not allow that. If that won't help, I'll try to move all queues to RAM and see. Thanks.
