Liferay启动时间太长了

Question

我是新的Liferay开发，我面临的麻烦与启动我的Liferay Tomcat服务器。它几乎需要3分钟（169048毫秒），这对于开发来说是不可接受的。我想把它压缩到一分钟左右。

以下是我的机器的规格：

• 英特尔酷睿双核T2300@1.66 GHz
• 4GB RAM（使用中3.24GB)
• 带有Service Pack 1Windows 7 Enterprise 32位

我正在使用：

• Liferay 6.1.1-Ce-GA2与Tomcat 7
• Eclipse IDE Juno版本

为了加快进度，我：

• 从Tomcat\webapps文件夹中删除了所有不必要的portlet。
• 将Tomcat本机库1.1.24放入Tomcat\bin文件夹
• 调整了我的portal-ext.properties，如下所示

     #disable some filters  
     com.liferay.portal.servlet.filters.sso.cas.CASFilter       = false
     com.liferay.portal.servlet.filters.sso.ntlm.NtlmFilter     = false
     com.liferay.portal.servlet.filters.sso.ntlm.NtlmPostFilter = false
     com.liferay.portal.servlet.filters.sso.opensso.OpenSSOFilter= false
     com.liferay.portal.sharepoint.SharepointFilter             = false
     com.liferay.portal.servlet.filters.gzip.GZipFilter         = false

     #disable indexing  
     index.on.startup=false

这是我的启动日志：

有什么建议吗？

评论已经给出了一些暗示。我想说，最重要的问题是检查是否使用了虚拟内存（分页）--一旦操作系统不得不将内存分页到磁盘上，您就输了：这可能是一个巨大的性能打击。

当您升级内存时（例如，如果您使用了虚拟内存），您可能要考虑将OS升级到64位OS-32bit只能处理4G，并且您可能会使用appserver内存达到极限，因为每个进程只能获得有限的内存。

您还可以在运行这么多其他应用程序之前测试Liferay是否启动得更快--这是您遇到内存问题的另一个暗示。

SSD选项将进一步加速您的系统，但价格远高于RAM。另外，在SSD上的虚拟内存并不是真的被推荐--它会更快地磨损驱动器。而不是在SSD上使用虚拟内存，而是不要使用虚拟内存--这样会更快更便宜。
