Apple JDK’s / OpenJDK’s – Core2Duo vs Core i7

Last Updated on Lundi, 18 avril 2011 07:57 Written by Henri Gomez Lundi, 18 avril 2011 07:39

Previously I did benchmark of Apple VMs and OpenJDK 6 and I wanted to see how all of the JVMs available today on our Mac on two systems, an old Core2Duo and a newer Core i7. And also see how they perform 32 / 64 bits kernel mode.

So I redo full dacapo bench suite to include OpenJDK 6, and we have now 5 VMs (3 Java 6 and 2 Java 7) :

• Apple Java 1.6.0_22 – Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03-314, mixed mode)
• Apple Java 1.6.0_24 – Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-348, mixed mode)
• OpenJDK 7 bsd-port – OpenJDK 64-Bit Server VM (build 21.0-b07, mixed mode)
• OpenJDK 7 macosx-port – OpenJDK 64-Bit Server VM (build 21.0-b07, mixed mode)
• OpenJDK 6 macports – OpenJDK 64-Bit Server VM (build 17.0-b16, mixed mode)

Results on MacBook Pro – Core2Duo 2.66Ghz – 32bits kernel

Results on iMac – Core i7 2.8Ghz – 64bits kernel

Conclusion

As seen if previous article, latest Apple JVM, 1.6.0-24 perform better than the old 1.6.0-22, and still behind OpenJDK 7 and even OpenJDK 6. OpenJDK 7 bsd-port is still faster (by a small factor) than OpenJDK 7 from macosx-port (built with LLVM), in both simple threaded (Core2Duo, 2 cores) and large threaded (i7 4 cores with hyperthreading).

This benchmark show how good is Intel Core i7 comparing to previous generation Intel Core2Duo, roughly twice as fast.

OpenJDK 7 on OS/X and IntelliJ IDEA EAP

During the last weeks, Apple started to contribute it’s Aqua/Cocoa port to OpenJDK 7 on the macosx-port branch. It’s still works it progress but it was nice to see some SWING apps like IntelliJ IDEA works on the preliminary release.

I used IntelliJ IDEA EAP (10.5) and tweaked it’s startup shell.sh to define AWT_TOOLKIT=CToolkit and add -Dswing.defaultlaf=com.apple.laf.AquaLookAndFeel since Aqua Look and Feel is not default for now.

export CLASSPATH

LD_LIBRARY_PATH=.:$LD_LIBRARY_PATH
export LD_LIBRARY_PATHAWT_TOOLKIT

# AWT/Cocoa port for OpenJDK 7 macosx-port
export=CToolkit
JVM_ARGS="-Dswing.defaultlaf=com.apple.laf.AquaLookAndFeel $JVM_ARGS"

cd "$IDEA_BIN_HOME"
while true ; do
  $IDEA_JDK/bin/java $JVM_ARGS -Djb.restart.code=88 $IDEA_MAIN_CLASS_NAME $*
  test $? -ne 88 && break
done

Then defined OpenJDK 7 from macosx port (available here) as default JVM and started IntelliJ by calling its shell script :

export JAVA_HOME=/Library/Java/JavaVirtualMachines/1.7.0.jdk/Contents/Home
/Applications/IdeaX-IU-106.396.app/bin/idea.sh

And I could see a Swing based application running on OpenJDK 7 and OS/X.

IntelliJ IDEA is so the second major IDE to be compatible with OpenJDK 7 and OS/X – Cocoa, first one was Eclipse thanks to it’s SWT/Cocoa bridge.
I tested with both NetBeans 7 RC1 and RC2 but it didn’t works. I hope it will be fixed in NetBeans 7 final release.
