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:+UseCompressedOopsGroup 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

1 楼 jwd001 2011-08-02   我简单的部署了个.war目录,请问为什么jsp修改后不能生效,非要重部署吗? 2 楼 jbosscn 2011-08-03   是的。这样jsp才能被重新编译。.war的目录要用.dodeploy来触发重新部署，.war文件不用。 3 楼 jwd001 2011-08-03   谢谢回复!我一直在用jboss4.2.3+jboss seam2. 看来要等到jboss7.1再使用. 4 楼 jwd001 2011-08-19   终于等到jboss7.0.1修复了这个bug. https://issues.jboss.org/browse/AS7-1509.
第一版真的要不得,不能心急.
