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).

Hi.
Using debian 8.0 on a raspberryPI SERVER, accessing nfs from another raspberry gives quick reply.
But from a slackware 14.1 SERVER on a Celeron 2Ghz dual core, is painfully slow and i cannot figure out why.
Can anyone guide me? (2 Replies)
