AS 7 startup time showdown

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.

 

When you start the server the first time, it starts slower than subsequent starts. We are interested in your best times

 

During the first startup, AS 7 builds caches and indexes and performs precompilations, "getting to know" your installation and libraries. The same optimizations are done on your deployments, so subsequent deployments are typically faster than the first.

 

On with the showdown! Feel free to edit this page and add your metrics. We are most interested in stock JVM settings, just to even the playing field. If you do add flags, please note that in the JVM column. We ask that you not step on previous entries.

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

 

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)

 

JVM flag legend (for table above):

 

  • Group A: -Xms64m -Xmx512m -XX:MaxPermSize=256m -client -noverify -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

 

Let the best machine win!
