Hello,

Wondering what's a good value for effective_io_concurrency when dealing with FusionIO drives...anyone have any
experiencewith this? 

I know that SSDs vary from 10 channels to 30, and that 1 SSD about as fast as a 4-drive RAID, but I can't seem to
settleon a good value to use for effective_io_concurrency.  Has anyone done any performance testing/metrics with the
value? Any recommendations or thoughts?
