Exactly what are you trying to compare, disk I/O, memory or cpu consumption. For disk I/O you can try running iostat, for memory run free or exmap, for cpu run top.

"top" is a command that lists the currently running processes and their CPU usage, as well as the total CPU load. Just try it and you'll see...
