HP-UX Performance Issue
I will brief here very strange and peculiar performance problem with two HP-Itanuim Servers
The Server details are
Rx2660 (Good Configuration but very bad performance)
CPU: Two dual core (1.42 GHz, 12MB 9120N) processor
Memory: 16GB
Disk: 146GB 10k SAS
OS version HP-UX 11.31 release Sep2009
N/W: 1gbps
Script runs time: 68 min
Rx4640 (Not that great Configuration as 2660 but very impressive and faster performance)
CPU: HP mx2 dual processor
Memory 8GB
Disk: 73GB
OS version HP-UX 11.31 release Sep2009
N/W: 1gbps
Script runs time: 20 Sec
When we run congnos script the script will get complete in 15sec on rx4640 vs. it takes more than hour (68min) on Rx2660.
When the congnos script runs it call DB which is running on other Server and choose the fields and performs insert to another DB. In this case both Servers ( 2660 & 4640) are connecting to same DB Server. Also the DB client is also same on both the Servers.
If I compare both Server CPU, memory, disk and N/W the Slower system (2660) has all good horsepower compare to rx4640 but, when performance comes it acts like 10year old box.
We have tried to bring both OS same version and all kernel parameters same but not able to understands why the performance differ with such huge unbelievable difference.
Really appreciate if we get faster response on this.

Re: HP-UX Performance Issue
Synchronous Page I/O error occurred while paging to/from NFS server qiublrboanfs001
file system is /home
Look suspicious in rx2660 logs. How much are /home and NFS involved?

Re: HP-UX Performance Issue
netstat -s > before.netstat
lanadmin -g mibstats
- run the cognos script -
netstat -s > after.netstat
lanadmin -g mibstats
where you replace
You can run the before and after files through "beforeafter" from ftp://ftp.cup.hp.com/dist/networking/tools
beforeafter before after > delta
and that will subtract all the numbers it finds in before from their counterparts in after - giving you the change over the interval.
