Terminology

Time Estimate

Prerequisite experience

Experience with profiling web applications

Background

Mifos requires a great deal of RAM (more than 1GB) and Java heap space (1GB), for nominal operation.

• Less tax on system resources
• Fewer out-of-memory errors in production and testing
• 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.
