Conditions

  • You must have a dual processor or quad core, (better if you use VMarg1)
  • You must start Eclipse with Java 1.6, note that you can still compile your project with Java 1.5
    (see windows - preferences - java - Installed JRE's)

The tricks is to use the optimization done in JDK 1.6 (VMarg2) and the new agresivity of the Just In Time
compiler (JIT) for VMarg3



Eclipse.ini 설정 파일을 열어서 추가한다.

-XX:-UseParallelGC
-XX:+AggressiveOpts
-XX:-UseConcMarkSweepGC

Some details about what these parameters are doing:

VMarg1 -XX:-UseParallelGC

Use parallel garbage collection for scavenges. (Introduced in 1.4.1) this will create more threads running in parallel, so the second processor will be put in use

VMarg2 -XX:-UseConcMarkSweepGC

Use concurrent mark-sweep collection for the old generation. (Introduced in 1.4.1)

The Eclipse GUI will feel more responsive as memory will be reclaimed without blocking VM executions.

VMarg3 -XX:+AggressiveOpts Turn on point performance compiler optimizations that are expected to be default in upcoming releases. (Introduced in 5.0 update 6.)
