Liferay初创公司需要太长时间

Fei*_*abi 9 performance startup liferay

我是Liferay开发的新手,我在Liferay Tomcat服务器启动时遇到了麻烦.这需要将近3分钟(169048毫秒),这对于开发来说是不可接受的.我想把它降到一分钟左右.

这是我的机器的规格:

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

我正在使用:

Liferay 6.1.1-ce-ga2与Tomcat 7捆绑在一起
Eclipse IDE Juno发布

为了加快速度,我做了:

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放在tomcat\bin文件夹中
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？

评论已经给出了一些提示。我想说，最重要的问题是检查是否使用了虚拟内存（分页） - 一旦操作系统必须将内存分页到磁盘，您就已经失去了：可能会造成巨大的性能损失。

当您升级内存时（例如，如果您达到虚拟内存），您可能需要考虑将操作系统升级到 64 位操作系统 - 32 位只能寻址 4G，并且您可能会遇到应用程序服务器内存的限制，因为每个进程只能获得有限数量的内存。记忆。

您还可以在运行许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提示。

SSD 选项将进一步加速您的系统，但价格比 RAM 高得多。另外，不建议使用 SSD 上的虚拟内存 - 它会更快地磨损驱动器。与其在 SSD 上使用虚拟内存，不如不要使用虚拟内存 - 这会更快、更便宜。
