4 Focus Areas for the Best ColdFusion Server Optimization

In this article, you will learn:

  1. How to configure the JVM
  2. How to tune the Garbage Collector
  3. Various steps to take for Performance Tuning
  4. How to improve your Web Server Connector

Six key areas CIOs must master

  1. The easy way is to run an automated detection tool such as CF Server monitor to help locate rogue memory processes. The server monitor is great for Enterprise Editions users. But what about Standard users? FusionReactor and its associated plugins can be a viable option.
  2. Then you have the hard way. If you are experiencing heavy memory leak without any indication from automation, you will have to manually inspect the code. This process requires you to manually enable and disable portions of code at a time. When doing this, you need to observe and take note of your memory usage rates. These rises and drops can give you clues as to where your memory leak may be hiding.

Tuning the Garbage Collector

  • Serial Garbage Collector
  • Parallel Garbage Collector
  • Concurrent Mark Sweep (CMS) Garbage Collector
  • G1 Garbage Collector
-XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=3 -XX:GCLogFileSize=10240k -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -XX:+PrintHeapAtGC -verbose:gc -Xloggc:convectiveGC.log

Tuning the Tenured Generation

  • Increase Xmx
  • Increase Xms

Tuning the Younger Generation

  • -Xmn
  • SurvivorRatio
  • TargetSurvivorRatio

Tuning with UseParallelOldGC

Tuning with MaxPermSize

Tuning with -XX: New Ratio
