General Benchmarking

I want a straighforward way of comparing two different systems in terms of their performance.

It does not seem that RedHat ships with any benchmarking utility of sufficient merit. I am looking for something comparable to Bench32.exe from Atto for Windows but I can't seem to find anything. Moreover, the benchmark utility in Disk Utility requires an unformatted disk to test write performance, but it is also able to take advantage of RAM. In this case I want to directly test DISK I/O performance and produce a nice plot of where the sweetspot is for the block size.

I'm curious as to what others are using to do this. Also any recommended CPU and memory benchmarking utilitites. They key is to keep it simple. I've looked at Phoronix Test Suite which is nice but a bit on the cumbersome side. It may come down to that though.

Any suggestions are welcomed.
