Liferay启动花费的时间太长 [英] Liferay startup takes way too long
问题描述
我是Liferay开发的新手，并且在启动Liferay Tomcat服务器时遇到了麻烦.它花费了将近3分钟(169048毫秒)，这对于开发来说是无法接受的.我想把时间降到一分钟左右.
I'm new to Liferay developing and I’m facing troubles with the startup of my Liferay Tomcat server. It takes almost 3 minutes (169048 ms) which is unacceptable for development. I’d like to get it down to about one minute.
这是我的机器的规格:
- Intel Core Duo T2300 @ 1.66GHz
- 4GB RAM(正在使用3.24GB)
- 带有Service Pack 1的Windows 7 Enterprise 32位
我正在使用:
- 与Tomcat 7捆绑在一起的Liferay 6.1.1-ce-ga2
- Eclipse IDE Juno版本
为了加快速度，我已经:
In order to speed things up, I’ve:
- 从tomcat \ webapps文件夹中删除了所有不必要的portlet.
- 在tomcat \ bin文件夹中放入Tomcat本机库1.1.24
- 如下所示调整了我的portal-ext.properties
#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?
推荐答案
注释已经给出了一些提示.我要说的是，最重要的问题是检查是否使用了虚拟内存(分页)-操作系统必须将内存分页到磁盘时，您就已经迷失了:性能可能受到巨大打击.
The comments already gave some hints. I'd say, the most important issue is to check if virtual memory (paging) is used - as soon as the OS has to page memory to disk, you have lost: There's a potentially huge performance hit.
在升级内存(例如，如果您访问虚拟内存)时，您可能要考虑将操作系统升级到64位操作系统-32位只能寻址4G，并且由于每个进程只能获得一个内存，因此您可能会遇到appserver内存的限制.内存量有限.
When you upgrade your memory (e.g. if you hit the virtual memory) you might want to consider upgrading the OS to a 64bit OS - 32bit can only address 4G and you might hit limits with appserver memory as each process can only get a limited amount of memory.
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.
You could also test if Liferay starts up faster before you run so many other applications - this is another hint that you're running into a memory issue.
SSD选项将进一步加速您的系统，但价格要比RAM高得多.此外，实际上也不建议使用SSD上的虚拟内存-它将使驱动器更快地磨损.而且，不要在SSD上使用虚拟内存，而是不要使用虚拟内存-这将更快，更便宜.
The SSD option will further accelerate your system, but for a much higher price than RAM. Also, virtual memory on SSD is not really recommended - it will wear out the drive quicker. And instead of using virtual memory on SSD, rather don't use virtual memory - this will be quicker AND cheaper.
