- Depending on the JDK you use,you can increase the maximum size of the permanent generation. Do this by starting Eclipse with
-XX:MaxPermSize=###m - Rulesets of 4000 rules or greater should have the permanent generation set to at least 128Mb.
- You can put rules in a file with the
.ruleextension. The background builder will not try to compile them every time there is a change which will help the IDE run faster.
