CPU and Disk Performance Test

[Hooovahh]

So I have a couple of NI controllers, and I want to know how they perform against one another.  Is there a set of VIs that is some kind of standard for testing the CPU usage, disk performance, and possibly ram? 

I basically just want to run a set of VIs on the RT controller, then see some numbers, then run the same test on another target and see how they compare.  Just for fun I'd be interested in running this same test on Windows too so cross platform G code would be preferred.  However these are all the Linux RT machines and if I can just run something through Linux, or the OPKG package that'd be fine too.  Thanks.
