performance checking by using time
Iam working on 2 hp servers of model 9000/800/L3000-8x which are having the same file system and both these servers are being replicated.
Iam having a performance problem on one of them.
when I try to check a extraction of a same zip file on both server1 and server 2 using the time command.
server1>time unzip xyp.zip
real 1:26.1
user 1.5
sys 2.3
server2>time unzip xyp.zip
real 20.3
user 1.7
sys 1.7
you can observe there is a huge diffrence in the time between server1 and server2.
Even the disk utilisation for server1 is much lesser than server2.
could anyone help me out on this problem?
thanks in advance
Rgds,
Ricky

Re: performance checking by using time
# top
# vmstat
# iostat
It will give you the way to tune. Hope the system configuration on swap, memory, processor are same.

Re: performance checking by using time
You need to check various stuffs in the system,
# top
# vmstat 5 5
# iostat
will help you. Also, SEP's system monitor script provide you with many details.

Re: performance checking by using time
You have posted one measurement and at that for a process that runs relatively quickly. You have little idea of how *other* processing, including I/O rates, queue depths and transfer times are impacting *your* process. A better analysis would begin with 'sar' and 'glance' performanace measurements. Overall, over time, there may be little real difference.
Regards!

Re: performance checking by using time
I have allready analysed using the sar,iostat and top and what I analysed is that the server1 which has considerable bad performance has good results of this and
below are few results
Average SAR
server1:
Average 6 8 1 85
server2:
Average 9 10 1 80
also iostat and vmstat could not help me out in identifying the difference.
I have also tested other processes on the two machines and found both are accomplishing the job alomost at the same time.
How can I check the queue depth?
Iam using the same unzip version and testing on the same file on both the machines.
Rgds,
Ricky

Re: performance checking by using time
You should check the load average for both servers.

Re: performance checking by using time
If you are really stuck get a trial copy of this http://www.sarcheck.com/index.htm
Seems to me they are not identical and one is doing a lot more disk io so slowing the rest
what does
w -l
Give on the 2 machines

Re: performance checking by using time
Do you have GlancePlus Pak installed?
Are you using PerfView or Performance Manager?
