Liferay startup takes way too long

Question

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.

Here are the specs of my machine:

• Intel Core Duo T2300 @ 1.66GHz
• 4GB RAM (3.24GB in use)
• Windows 7 Enterprise 32 bit with Service Pack 1

I’m using:

• Liferay 6.1.1-ce-ga2 bundled with Tomcat 7
• Eclipse IDE Juno Release

In order to speed things up, I’ve:

• removed all unnecessary portlets from the tomcat\webapps folder.
• put the Tomcat native library 1.1.24 in the tomcat\bin folder
• tweaked my portal-ext.properties as shown below

     #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

Here’s my startup log:

Any suggestions?

Answer 1

The server speed depends so much on a well configured JVM (memory, garbage collector type, etc) and Tomcat connector thread pool. depending of available server resources. Liferay provide a recommended configuration:

`-server -XX:NewSize=1024m -XX:MaxNewSize=1024m -Xms4096m
-Xmx4096m -XX:MetaspaceSize=300m -XX:MaxMetaspaceSize=300m
-XX:SurvivorRatio=12 –XX:TargetSurvivorRatio=90 –
XX:MaxTenuringThreshold=15 -XX:+UseLargePages
-XX:LargePageSizeInBytes=256m -XX:+UseParNewGC
-XX:ParallelGCThreads=16 -XX:+UseConcMarkSweepGC
-XX:+CMSParallelRemarkEnabled -XX:+CMSCompactWhenClearAllSoftRefs
-XX:CMSInitiatingOccupancyFraction=85 -XX:+CMSScavengeBeforeRemark
-XX:+UseLargePages -XX:LargePageSizeInBytes=256m
-XX:+UseCompressedOops -XX:+DisableExplicitGC -XX:-UseBiasedLocking
-XX:+BindGCTaskThreadsToCPUs -XX:+UseFastAccessorMethods
-XX:InitialCodeCacheSize=32m -XX:ReservedCodeCacheSize=96m`

The above JVM settings should formulate a starting point for your performance tuning. Each system’s final parameters will vary due to a variety of factors including number of current users and transaction speed.

In tomcat servers you define this configuration like CATALINA_OPTS environment variable in /[tomcat_server]/bin/setenv.[sh or bat] file.

Answer 2

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.

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.

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.

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.

Answer 3

This problem is solved by upgrading to Liferay 7.

While Liferay 7 does not start faster, developers really never need to restart it, as everything can be overridden by deploying new OSGi components. That is actually the biggest difference between Liferay 6 and Liferay 7.

I have been developing for Liferay 7 for 3 months, including very deep customization (for instance intercepting all file reads for audit), and have never needed to restart the Liferay server.
