Hi!
Also, with both languages, you will have an IO bottleneck.
Yes IO is really the bottleneck I have seen that.
You can greatly reduce IO wait if you write the data to a different disk
than you read from. Speed up things even more, consider using a hardware
RAID controller with write cache (i prefer 3ware 9000 series; but
whatever makes you happy). You should use the RAID controller even if
you use two single disks, since most of them have the capabilities to
offload a significant amount of processing.
Also, using Raid10 on SAS disks will give you even more speed.
While processing power is nowadays (mostly) a software problem, good
ole' cash will still solve most of your IO wait problems.
