Performance testing/tuning Alfresco Share 3.2r

[mikkoko]

Hello

I have configured a Share site (Alfresco Community 3.2r) that sits behind Apache httpd and mod_jk + mod_ssl. The installation is in CentOS 5.4 on a XenServer virtual machine with 4GB RAM and 2 VCPUs with full priority.

I have gotten reports that the system is quite sluggish sometimes, while at other points it works just fine. Based on my tests I can confim this, for example pdf2swf / openoffice.org conversions sometimes take minutes to complete while at other points they work right away. The general UI feel also could use a bit of tuning.

Basicly what I'd like to hear is other peoples experiences in testing and tuning Share performance and tips on how to go about doing it.

I have little experience in Tomcat / Alfresco, which I guess are the targets to go after, I don't think the problems lie in Apache or mod_jk

Thanks for any input..

OpenOffice can be a resource drain - especially when converting large PowerPoint presentations.

You might want to consider running OpenOffice on a separate server. See http://wiki.alfresco.com/wiki/Running_OpenOffice_From_Remote_Machine for information.

People are also experimenting with an OpenOffice Server Daemon which would be useful in an EC2 deployment, for example: http://oodaemon.sourceforge.net/

Thanks,
Mike

Hi,

We're running a setup that is almost the same as yours. We've only got about 7-10 concurrent users, which does cause our system to get a little bit slow, but not noticeably. Have you tuned your JVM paramters for Tomcat?

We're running the following JVM options below right now, and the system has been running fairly smoothly. Basically we've got 2GB of RAM allocated to Alfresco/Tomcat, and another 2GB for everything else (e.g. Linux/Apache/MySQL/PHP).

-Xms512m -Xmx2048m -XX:MaxPermSize=256m -server

We're running a dual CPU 3.16GHz, 4GB RAM machine on RedHat 5.4.
