improving performance with connector params

[me...@assetmanagement.natexis.fr]

We're running Tomcat 4.1.18 with jdk1.3 under linux 
The communication with apache is set via the Webapp Connector.

In order to improve performance I need some suggestions
about the connectors attributes.

The extract below is from our server.xml file in the
prod environnement

<Connector className="org.apache.catalina.connector.warp.WarpConnector"
     port="8008" minProcessors="5" maxProcessors="75"
     enableLookups="false" appBase="webapps"
     acceptCount="10" debug="0"/>
 
 
the only thing we've changed is the enableLookup attribute.
For thoses who are used to manage these attributes, I'd
like you to help me making the right choice about setting 
right values to the other attributes(max and minProcessors
and acceptCount).

In the prod environnement, the machine is dedicated to Tomcat
only and I assume that we could increase the maxProcessors value.
I'm tempted to say that we could increase the acceptCount too but
without any real experience about.

Any suggestion would be greetly appreciated.

Re: improving performance with connector params

[Antonio Fiol Bonnín <fi...@terra.es>]

It is not really a performance issue, but you will need to increase 
maxProcessors to the MaxClients value you have in your Apache web server 
in front.

If you have something other than Apache, it will not be called 
MaxClients, but you get the idea...

I would not raise acceptCount unless you know why.

Hope that helps,


Antonio Fiol
