Ability to run Mifos in a 64-bit JVM with less than 8GB RAM
Cheaper to host Mifos

Details

analyze memory usage of the Mifos web application while under deployment in a servlet container such as Tomcat
reduce Mifos web application memory footprint by at least 50%
Tools such as JProfiler, visualvm may be helpful.
