RSA7 and Local WebSphere Test Environment Performance Tips

If you’re encountering slowness in either your RSA IDE or in the embedded WebSphere Test Environment, here several strategies that may help:
RSA7 Performance
- In c:\Program Files\IBM\SDP70\jdk\bin run this: “java -Xshareclasses:destroyAll”. This will delete a cache file in C:\Documents and Settings\<username>\Local Settings\Application Data\javasharedresources.
- Run “C:\Program Files\IBM\SDP70>eclipse –clean” This is supposed to clean up some other cached data.
- Edit eclipse.ini (C:\Program Files\IBM\SDP70\eclipse.ini) to change the “-Xshareclasses:singleJVM,keep” line to “-Xshareclasses:none”
- Edit eclipse.ini to have larger max heap (e.g. 768m), and set min heap equal to max.
- Try increasing the MaxPermSize in eclipse.ini (e.g. 512M).
- Update RSA7 to the latest fixpack.
- Try disabling automatic build; use Ctrl-B instead.
- If using JIBX, try removing the JIBX compiler from the builder list and running manually when needed.
- Try disabling the “AOP Reference Model Builder” builder if you’re using Spring IDE.
WAS 6.1 Test Environment Performance
- Update the WAS test env to the latest fixpack.
- Verify that automatic publishing is turned off.
- Restart applications via the “Restart” menu option instead of the “Publish” option on the application server.
- Set the min / max heap for WAS JVM to same size and larger, like 768 or 1024
Both
- Be aware that virus scan real time protection on most computers will significantly degrade disk IO. Also be especially careful that no scheduled scan is currently running.
- Also beware that laptops running PointSec full disk encryption can expect at least a 50% degradation in disk IO performance vs. a non-encrypted file system.
- If you have at least 3GB of memory, try reducing paging file size to very low to minimize paging.
