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.
