Alfresco Performance Problem

Question asked by jvehent on Oct 29, 2009
Hi there,


I'm setting up Alfresco Community 3.2 on a Linux Debian server and I'm experiencing performance issue with the Share component.

My setup works perfectly with Alfresco Explorer. I use LargePages (hugetlbfs) and my SUN JVM starts as follow:

/usr/lib/jvm/java-6-sun/bin/java 

-Xms1g -Xmx1g -XX:NewSize=300m -Xss1024k
-XX:MaxPermSize=128m -server -XX:+UseLargePages

-Dalfresco.home=/etc/alfresco -XX:CompileCommand=exclude,org/apache/lucene/index/IndexReader$1,doBody -XX:CompileCommand=exclude,org/alfresco/repo/search/impl/lucene/index/IndexInfo$Merger,mergeIndexes -XX:CompileCommand=exclude,org/alfresco/repo/search/impl/lucene/index/IndexInfo$Merger,mergeDeletions -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.util.logging.config.file=/etc/alfresco/tomcat/conf/logging.properties -Djava.endorsed.dirs=/etc/alfresco/tomcat/endorsed -classpath :/etc/alfresco/tomcat/bin/bootstrap.jar -Dcatalina.base=/etc/alfresco/tomcat -Dcatalina.home=/etc/alfresco/tomcat -Djava.io.tmpdir=/etc/alfresco/tomcat/temp org.apache.catalina.startup.Bootstrap start

/proc/meminfo shows the correct use of LargePage

$ grep -i huge /proc/meminfo
HugePages_Total:   350
HugePages_Free:     71
HugePages_Rsvd:      9
HugePages_Surp:      0
Hugepagesize:     4096 kB

As I said, Alfresco Explorer works perfectly fine (fast, not error). But when I try to use Alfresco Share, the login process takes forever and when I finally reach the dashboard, I get the following message in some of the boxes :

An error has occured in the Share component: 
/share/service/components/dashlets/my-sites.
It responded with a status of 500 - Internal Error.
Error Code Information: 500 - An error inside the HTTP server which

I can still browse the sites, but it's really slow (around 20 secondes to 1/2 minutes per request).

Can you please help me fix this issue?   :?:
