--------------------------------------------------------------
How fast does AS 7 start on your computer? This page is a crowdsourced benchmark to see what type of times people are getting. It could also give you an idea if it's time to upgrade your computer to more cores.

Start-up times may vary sligtly between different runs, due to system load, filesystem caching etc. We are interested in your best times  :) 

On with the showdown! Start JBoss AS 7 in standalone mode and add your results to this page. We are mostly interested in *stock JVM settings*, just to even the playing field. If you add flags, please note that in the JVM column.

h3. JVM flag legend (for table above)

* *Group A*: -Xms64m -Xmx512m -XX:MaxPermSize=256m -client -Xverify:none -XX:+UseFastAccessorMethods -XX:+DisableExplicitGC -XX:+UseCompressedOops
* *Group B*: -server -Xms128m -Xmx128m -XX:MaxPermSize=128m -Djava.net.preferIPv4Stack=true -XX:+UseFastAccessorMethods -XX:+TieredCompilation -Xverify:none

h3. Optimizations

You get better startup times with 32 bit over 64 bit, because of the smaller integer size. If you are on a 64 bit machine, you can do one of two things to get 32 bit performance:

* Run in 32 bit mode using the JVM flag: -d32 (Mac and Windows)
* Use the JVM compression flag: -XX:+UseCompressedOops (option not valid on a 32 bit JVM)

There are also some other JVM flags that will speed things up:

* -noverify
* -XX:+DisableExplicitGC
* -client (32 bit JVM only. You have to edit standalone.sh to use -client instead of -server)

You can squeeze out a few fractions of a second by disabling the console logging (or directing it to /dev/null):

./standalone.sh > /dev/null

You can still view the log output by tailing the server log.

See comments for other suggestions.

Let the best machine win!
