I am presenting here some tools that could be useful when facing performance issues on HP-UX.
Glance is a very powerful online performance diagnostic tool where you can find almost all you need in order to figure out what could happen in the system, performance related of course. The tool is interactive, like top for example, and you can go trough its features with various shortcuts. Find below some of them:

How to find out which processes are using more memory:
gz-hp-ux:/# top -f top.out -n 10000 -d 1
gz-hp-ux:/# sort -n -k7,7 top.out
gz-hp-ux:/# sort -n -k7,7 top.out | awk '{if ($7~/M$/) {print $0}}'
Sar command is also very powerful and you can find it in hp-ux. For example, with the options below, you can list a report activity for each lunpath:
Report activity for each active lunpath:
gz-hp-ux:/# sar -L 2 2

And, of course, you can tune some parameters with kctune command. This is the administrative command for HP-UX kernel tunable parameters. Find below some examples:
To see all tunables and their current values:
gz-hp-ux:/# kctune
To see which tunables have new values being held until next boot:
gz-hp-ux:/# kctune -D
To To see the tunables with only non default value
gz-hp-ux:/# kctune -S
To see verbose information about a tunable:
gz-hp-ux:/# kctune -v tunablename
To set a tunable value on the running system:
gz-hp-ux:/# kctune tunable=69
To set a tunable value to be used when the system reboots:
gz-hp-ux:/# kctune -h tunable=69
To increase a tunable's value by 99:
gz-hp-ux:/# kctune tunable+=99
