Java VM tuning - Xbatch and -Xcomp

Question

I am looking at the JVM configuration options for running Alfresco, mainly this document on the Alfresco Wiki. One of the recommendations is to use the JVM flags -Xcom

Answer 1

Alfresco is an Enterprise Content Management. I am not sure how the flags affects its performance. Then a note in the same page said..

-- This will, however, significantly increase the server startup time, but will highlight missing dependencies that can be hit later. ...

IMHO, The author did not really mean a performance gain. He/she wrote it as means to check all dependencies are in place.
