Servlet containers, startup time

Last Updated on Vendredi, 15 juillet 2011 01:12 Written by Henri Gomez Vendredi, 15 juillet 2011 12:11

With the release of JBoss AS7, we see many comments around about the startup time of Application Servers.
Even if this appears marginal in real life (an application server is expected to run 24/24 7/7), there is area where startup time is still important like for developpers. In developpment phase, when you have to start/stop your server dozens of times by day, you need fastest start time as possible.

I conducted a very basic and simple test on my MacBook Pro, take various application servers and servlet containers and measure their startup time.

And in this days of Java 7 fever, try these servers with OpenJDK 7 (OS/X version).

Apple JDK’s / OpenJDK – back to benchs

It’s good to see works in progress for Aqua/Cocoa – AWT ports but what about JVM performances ?

Test vms

I selected 4 VMs to be tested


Apple Java 1.6.0_22 - java version "1.6.0_22"
Java(TM) SE Runtime Environment (build 1.6.0_22-b04-314-10M3406a)
Java HotSpot(TM) 64-Bit Server VM (build 17.1-b03-314, mixed mode)



Apple Java 1.6.0_24 - java version "1.6.0_24"
Java(TM) SE Runtime Environment (build 1.6.0_24-b07-348-10M3406a)
Java HotSpot(TM) 64-Bit Server VM (build 19.1-b02-348, mixed mode)



OpenJDK 7 bsd-port - openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build 1.7.0-internal-henri_2011_04_11_08_24-b00)
OpenJDK 64-Bit Server VM (build 21.0-b07, mixed mode)



OpenJDK 7 macosx-port - openjdk version "1.7.0-internal"
OpenJDK Runtime Environment (build 1.7.0-internal-b00)
OpenJDK 64-Bit Server VM (build 21.0-b07, mixed mode)


Test system

My test system is an Apple iMac (iMac11,1 ) with Intel i7 2.80Ghz and 8Gb DDR3 1067Mhz, running under SnowLeopard 10.6.7 64bits.
I wanted to test 64bits VMs on a 64bits machine and this time use a stronger processor with more threads (ie: 4 cores with hyperthreading).

DaCapo Benchmarks

I keep the DaCapo 9.12-bach.

Bench tests launched with -n X, ie (java -jar dacapo-9.12-bach.jar -n 10 pmd)

Conclusion

Latest Apple JVM, 1.6.0-24 perform better than the old 1.6.0-22 in all of the tests and is near OpenJDK 7 results.

OpenJDK 7 from the bsd-port perform a little better than the macosx-port. The main difference in build is bsd-port is using stock gcc whereas macos-port use llvm-gcc.

Performances gain in OpenJDK7 VM vs latest Apple 6 VM is smaller than previously (see previous articles on Apple JDK vs OpenJDK 6), switching to OpenJDK 7 will not be only for pure speed but for functionalities.

OpenJDK 7 on OS/X and IntelliJ IDEA EAP

Last Updated on Samedi, 16 avril 2011 02:20 Written by Henri Gomez Samedi, 16 avril 2011 02:16

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.
