The "glance" program has more options which help find bottlenecks.
Press ? to get the menu or start glance with the option "e.g. glance -t".


In your case these should help:

w (swap activity)
t (system tables) Need to see all pages of this.
m (memory)
B (Global waits)
N (NFS)


First impressions are that you are short of memory but the above glance options should show an overview of what is happening. If you have pseudo-swap configured this can skew the memory figures.


BTW. The vmstat would mean more if we knew the sampling interval (i.e. the command line you typed).
