Tomcat 8 - Serving Static content extremely slow...

B_ Normann P_ Nielsen

After upgrading my Confluence to newest (and hence Tomcat 8), serving some static content became extremely poor in performance.

I have the AllowLinking=true, so some js scripts and css resources could be fetched from the filesystem. No problem until Tomcat 8, where the time from the server went to:

Uploading the files to Confluence and making a link to /download/xxxxxxx/filename.js solved the issue, and the time for the 2 files is roughly around 64ms per file. This is an acceptable solution, as migrations and stuff gets a bit simpler, but still... why the extreme poor performance. No changes to OS og Filesystem or similar, just the upgrade.....

Afterwards I have swiched from Apache2 to NGIX and killed a lot of old not used plugins to finetune.

Hi Normann,

If you upgraded Confluence out-of-the-box, it's more likely that you're with the default memory settings. Would you mind checking the following?

To increase the JVM memory, here are the steps:

Linux:

# From <confluence-install>/bin (Stand-alone) or <Tomcat-home>/bin (EAR-WAR installation), open setenv.sh (you can create this file in the EAR/WAR version).
# Find the section JAVA_OPTS="-Xms256m -Xmx512m -XX:MaxPermSize=256m ...
# See Diagnosis above and enter the appropriate values. Xmx is maximum, Xms is minimum, and MaxPermSize is PermGen.

Windows:

# From <confluence-install>/bin (Stand-alone) or <Tomcat-home>/bin (EAR-WAR installation), open setenv.bat.
# Find the section set JAVA_OPTS=%JAVA_OPTS% -Xms256m -Xmx512m -XX:MaxPermSize=256m
# See Diagnosis above and enter the appropriate values. Xmx is maximum, Xms is minimum, and MaxPermSize is PermGen.

Running Confluence as a Service:

Hi Normann,

I am not sure of your network setup, but you can add the following to your Connector parameter within server.xml:

<Connector port="8575" connectionTimeout="20000" redirectPort="8443"
maxThreads="200" minSpareThreads="10" compression="on"
compressableMimeType="text/html,text/xml,text/plain,text/css,application/json,application/javascript,image/gif,image/jpg,image/png"
protocol="org.apache.coyote.http11.Http11NioProtocol"
enableLookups="false" acceptCount="10" debug="0" URIEncoding="UTF-8" />

That should help with delivery of the static resources. In the alternative, you could use an Apache front-end to cache the static resources for delivery to end users as well.

Sincerely,

Chuck

Current config (as before): -Djava.util.logging.config.file=/opt/confluence/conf/logging.properties -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -XX:-UseAESIntrinsics -Djava.awt.headless=true -Xloggc:/opt/confluence/logs/gc-2015-09-17_18-42-22.log -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=2M -XX:-PrintGCDetails -XX:+PrintGCTimeStamps -XX:-PrintTenuringDistribution -Xms2048m -Xmx2048m -XX:MaxPermSize=1024m -XX:+UseG1GC -Djava.endorsed.dirs=/opt/confluence/endorsed -Dcatalina.base=/opt/confluence -Dcatalina.home=/opt/confluence -Djava.io.tmpdir=/opt/confluence/temp I always (after upgrade) - need to change settings in setenv.sh - And I can for sure set it higher, but this is a small website for my personal use only .... But thanx for the answer :-)

Sounds interesting, and Apache has always been the frontend - but I dont want to "disconnect" resources to much from the Confluence Instance. I will look into the compression though....

Remo Siegwart

We've experienced similar issues with custom and even Confluence supplied JS files: https://jira.atlassian.com/browse/CONF-39298 In our case, it looks like only JS files are affected by this issue.

I had to also add `useSendfile="false"` to the Connector element in order for the compression to work.
