Rational Requirement Composer Response time is very slow as compare RTC and RQM

Avtar Singh (1●7●7) | asked Jun 19 '14, 1:22 a.m.
Dear All,

We have CLM 4.0.1(RRC+RTC+RQM) at our site. All applications deployed on single server.

During use of all three application we found one issue that response time of Rational Requirement Composer is more than other two applications(RTC & RQM). I mean to say in simple language RRC is slower than RTC and RQM.

Can anybody help us out to identify the issue and solution.

Thanks in advance.

With Regards,
Avtar Singh

Performance issue can be quite complicated. Please open a ticket with IBM Support so that the system configuration can be reviewed and data collection can be appropriately carried out.

Hi Avtar,

I agree with Donald, but the main difference between those applications is the use of the indices.  Rational Requirements Composer is very dependent on the disk speed of the machine and the available RAM.  If you're seeing poor performance in only 1 of the 3 applications, then it is less likely to be threads; JVM heap etc...although I am not ruling it out.

There are many dependencies, but the most basic monitoring would be on the available RAM (RRC caches the indices, so basic rule of thumb would be to have at least the size of your indices <JAZZ_HOME>\server\conf\jts\indices on disk available as RAM).  Then also check your disk speed and ensure you're not using slow disks or NFS mounted drives.

My colleague Ben Silverman wrote this excellent article in the deployment wiki which you will find very useful:

Kind regards.
