18.20. Tips for Working with Large DRL Files

  1. 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
  2. Rulesets of 4000 rules or greater should have the permanent generation set to at least 128Mb.
  3. You can put rules in a file with the .rule extension. The background builder will not try to compile them every time there is a change which will help the IDE run faster.
