is this good or bad? hda2 is my swap partition:

# swap partition while mounted with one millllion processes
/dev/hda2:
 Timing buffer-cache reads:   128 MB in  0.99 seconds = 129.29 MB/sec
 Timing buffered disk reads:  64  MB in 21.93 seconds =   2.92 MB/sec

# swap partition unmounted with really only the bare essentials (22
# processes) running
/dev/hda2:
 Timing buffer-cache reads:   128 MB in  0.97 seconds = 131.96 MB/sec
 Timing buffered disk reads:  64  MB in 21.61 seconds =   2.96 MB/sec
