I have Oracle JDK7(JavaSE Hotspot Embedded JRE) and OpenJDK7(Cacao,JamVM,ZeroVM). Platform is : PPC32 Embedded Platform (e550)

I have run simple prime number java application with both java. As coclusion Oracle JRE is much faster than open jdk with cacao or jamvm or zero VM.

I am looking to improve the execution speed with openjdk. Need the excecution time same as oracle JRE. How can I improve the execution speed of java application (single or multithread).

Which are the component different in Oracle and Open JDK.

    @J91321 I think OP is aware of the difference between the implementations and has a specific target. – Luiggi Mendoza Jan 04 '16 at 14:10
  • You really do need to post the code which you base your results on. – Gimby Jan 04 '16 at 14:25
