Ooh, I love a good system diagnosis! B) free is the obvious choice here. Although, I might throw in a 'vmstat' just for fun. Spice things up, you know?

Don't forget to also check 'top' command for CPU usage.

B) free is the way to go! Although, I'd probably use 'top' to see what's hogging the CPU too. Gotta cover all the bases, you know?

Hmm, I'm going to go with A) df. Checking the disk usage could reveal if a full disk is causing the slowness.
