JBoss7的启动时间:0.7秒
(整理翻译By Jim Ma)
Dan Allen 创建了wiki 来征集jboss7启动的最快时间，并且对比了AS6的启动时间。如果你已经运行了AS7,别忘记到这个wiki更新你的启动结果。
这个两个表是AS7和AS6的启动时间对比，目前最快的是tkonishi的706ms. 这意味着当你敲完enter键，AS7就已经启动好了:

JVM设置:
- stock setting : 标准设置启动采用standalone.sh
- 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
优化启动时间:
由于更少的整数位，AS7在32位机器上比在64位机器上启动要快。如果你运行在64位机器上，你可以做以下设置来获得和在32位机器上同样的启动速度:
- 使用flag来运行到32位上: -d32 (Mac and Windows)
- 使用JVM compression flag: -XX:+UseCompressedOops (只适用于64位JVM)
下面这些JVM flags也有助于提高启动速度:
- -noverify
- -XX:+DisableExplicitGC
- -client (32 bit JVM only. You have to edit standalone.sh to use -client instead of -server)
关闭console的log(或者重定向到 /dev/null):也有助于加快启动速度:
./standalone.sh > /dev/null
