I see from the forum that I'm not the only one who has noticed big performance problems with Liferay. I did see the link to http://www.liferay.com/community/wiki/-/wiki/Main/Performance and I hope it helps, but I am very surprised that out-of-the-box performance is so slow. I downloaded Liferay 6.0.1 Community Edition (Tomcat bundle), started it up and began clicking around the 7cogs demo -- seems like everything I click on takes 5 to 10 seconds to process. I figured it was just the Hypersonic HSQLDB that was slow, so I added portal-ext.properties to use MySQL instead, but I hardly saw any improvement. Host workstation was Windows XP, 2.8GHz cpu, 1GB RAM.

So I guess this is a general Liferay question and not portal/portlet-specific, but can you comment on Liferay performance? Are you surprised to hear how slow it is, or is it a known problem with the latest release?

Thanks.

Hello,

It looks to me like this is your problem:
Host workstation was Windows XP, 2.8GHz cpu, 1GB RAM.


Liferay's JVM is set by default to 1024M (1GB), which is what it requires. So your system is out of memory and is swapping if you only have 1GB total.

Just had to reply to this one.

Intel i7 2600k, 8GB ram, SSD HD, Liferay CE 6.0.6 on Jetty slow as molasses...

OMG, reminds me of developing with Alfresco...
