Test-System: RT 4.05 
Ubuntu:  10.4.3 Lucid  

Hello everybody 

We have an RT 3.8.9 System running in an Prod Environment 

Now i tried to find out the best Settings for the new RT-Version 4.0.5 that
we can migrate asap. 

But Rt 4.0 seems to slow ( especially the loadingtime from a webif page)  to
beat our Prod. One.

Maybe my settings aren't correct or i should use an other webhandler 

okay now here the facts:

reconfigure rt with  the webhandler flag for fastcgi: ./configure 
--with-web-handler=fastcgi

test  dependencies: make fixdeps 

Webhandler: fcgid

RT_SiteConfig: 

Set( $rtname, 'example.com');


1;


Set($JSMinPath, '/opt/rt4/bin/jsmin');


Set($WebPath, "/rt");

Set($WebDomain, '192.168.xxx.xxx')



apache config: 

 rt4.0fcgid


<VirtualHost 192.168.112.22 >

AddDefaultCharset UTF-8
AddHandler fcgid-script .fcgi

        Alias /NoAuth/images/ /opt/rt4/share/html/NoAuth/images/
        ScriptAlias /rt  /opt/rt4/sbin/rt-server.fcgi

        DocumentRoot "/opt/rt4/share/html"
        <Location />
            Order allow,deny
            Allow from all

            Options +ExecCGI
            AddHandler fcgid-script fcgi
        </Location>

 </VirtualHost>


and here is the 
fcgid config: 

<IfModule mod_fcgid.c>
  AddHandler	fcgid-script .fcgi
  FcgidConnectTimeout 20

</IfModule>



Maybe someone know some hints or tipps to speed up my rt 4.0 instance  

best regards
