Do VMs really take this much of a hit in random I/O performance? I have a guest that only gets about 7,500 4K IOPS (64 threads) while the host can get upwards of 125,000.

Has anyone else done any benchmarking of SSDs inside of VMs? I'm curious if it's just a VirtualBox thing.
 
whats the specs of the host box hardware?

Ive found virtualbox running on my desktop box gets better performance than my hp server, and none of it is ssd
 
It's a pretty beefy system

Dual X5650s @ 4GHz
48GB DDR3-1600
4x Intel 520 Series, 120GB each, in RAID0
(on LSI 9260-4i w/ FastPath)
