 Hi,

Following a series of performance and network issues, our IT administrator has recommended to apply compression in the Tomcat configuration file.

That is, to add the following line in the server.xml file -

<Connector URIEncoding="UTF-8" acceptCount="100" connectionTimeout="20000"
disableUploadTimeout="true" enableLookups="false"
maxHttpHeaderSize="8192" maxSpareThreads="75"
maxThreads="500" minSpareThreads="25" port="9089"
redirectPort="9080" compression="on"
 compressionMinSize="2048" 
noCompressionUserAgents="gozilla, traviata"
compressableMimeType="text/html,text/xml, text/javascript,text/css,application/javascript" />

By doing this change,  will it impact the system in anyway and are there any case studies that this has improved the performance/network problems?

Hi Sunita,
Maybye it is not direct answer on your question but might help you.
See https://jazz.net/jazz/web/projects/Jazz%20Foundation#action=com.ibm.team.workitem.viewWorkItem&id=113717 comment 2 which indicates that default settings are fine.

Also according to https://jazz.net/forum/questions/75418/when-data-compression-happens-client-or-server scm data is compressed as default.

Let us know if it helps.

Hi Krzysztof, On the Jazz admin page, the compressed setting seemed to be ON. However, on the Tomcat server.xml, the compression parameters are commented. Are these compression parameters in the server.xml for a different purpose then ?

Hi Pavithra,
The settings for server.xml apply to entire communication. Options in advanced properties apply only for scm actions.

Anyway SCM action usually create the biggest traffic in RTC.

 So in your opinion, is it recommended to set the compression in Tomcat as well ?
