Thanks Chris for reply. Clarion is SAN, so all are data and OS partitions are on SAN.
Whole server works fine but our application works using tomcat and I have installed around 20 instances of tomcats on one virtual machine (2.66GHz and 4GB RAM). On similar line, does JDK takes advantage of two CPU compared to one CPU? I can reconfigure Swap file on separate disks than OS disk and see if it performs better. Please let me know if above info helps in understanding issue better?

AFAIK, there are no Tomcat-specific vmware issues. However, there could be some problems with the JVM in general that you might be coming across. For instance, if you are using a source of randomness that blocks when used through the virtual environment, that might cause a problem. Also, if you are using non-native disks (meaning a big file on the host OS that holds the entire filesystem for the VM), you may experience some slowdown, there. I'm not sure what Clarion is... could that be a problem at all? - -chris -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iD8DBQFG+DOF9CaO5/Lv0PARAtSKAJ0T6KHaEBu8WC6c9QSnea0QWtj/8QCguIhp VSqAodugC0GLy8LRk5In52I= =nMgC -----END PGP SIGNATURE----- --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] --------------------------------------------------------------------- To start a new topic, e-mail: users@tomcat.apache.org To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
