Next time you experience slowness, regardless of which volume you're booted into, launch /Apps/Utilities/Activity Monitor, select "All Processes" from the drop-down, click on "%CPU", and continue working.
If your slowness is a result of a process hogging system resources, the process should rise to the top of the list and show a high CPU use %.
