Re: system responding slow.
Look for memory leaks:

Performance check scripts:
http://www.hpux.ws/?p=6
glance or gpm to see what processor is running.
Terminal emulator is meaningless here.
Use a Linux box perhaps.
ssh -X hostname gpm
OR use an X windows front end like Hummingbird or CRX

Re: system responding slow.
And Glance will run just fine in TUI mode, so your terminal emulation should not be an issue.

Re: system responding slow.
and glance is your best bet as the starting point. Once you discover the root cause of the slowness, i.e., disk bottle neck, network bottleneck, CPU or Memory exhaustion, you will be able to figure out the next steps.

Re: system responding slow.
Responding slow---
Is it responding slow for every command?
Or is it slow for any specific files system/application.
Try to narrow this.
If it is entire system that is slow, try finding out where is bottleneck.
Use sar with different option to check disk, cpu bottlenecks.
Use swapinfo to find if memory is an issue.
Use top to find if any application is using more than usual memory.
If any application or accessing fs is slow, look at the disks involved.

Re: system responding slow.
system responding slow,
Your check points
1]If database is there, please check for number of active and inactive sessions.
2]Memory/CPU checks
Using,
#top- Check top resource taking process and whther these are running or not.
#Glance -Will give u detailed output, you get the exact count of memory,cpu and swap utilisation.
#vmstat -Check number of blocked process.
swap devices/ shared memory segments
Well some times processes completes but still dont release memory segmaents which can cause swap utilisation high ultimately slow response.
So, check
#ipcs -mob
in this if you find NATTCH parameter value as "0" the process you can relase using
#ipcrm -m
3]disk utilisation,
Please check using perticular disk is casing more outage.
Thease are some key checks u can go through.

glance
glance -m (or hit m whilst in glance)
glance -l (or hit l whilst in glance)
glance -u (or hit u whilst in glance)
and
uptime.

Re: system responding slow.
HP or Wyse or DEC -- the emulator is important. What is critically important is to never lie to HP-UX about your emulator. That means that there must never be something like:
TERM=vt100
export TERM
in /etc/profile or $HOME/.profile. Instead, you replace every hardcoded TERM= line with the terminal identifier: ttytype. Use it like this:
eval $(ttytype -s)
To see what this command will do, just type: ttytype -s. Now truly dumb terminals like vt100 will have no navigation keys (like f1, f2, f3, etc) but a smart terminal such as Reflection for HP or QCterm will have the function keys enabled.
