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?
