i'm using python wsgi application for an embedded web ui. i'm loading 
mod_wsgi dynamically over apache which takes a significant amount of time 
as compared to other modules. the load is happening at each device boot-up 
and is causing the boot-up time to slow down. the apache server details are 
as below --

Server version: Apache/2.2.21 (Unix)
Server built:   Sep 11 2012 17:26:04
Server's Module Magic Number: 20051115:30
Server loaded:  APR 1.4.5, APR-Util 1.3.12

  threaded:     no
    forked:     yes (variable process count)
Server compiled with....

 -D DEFAULT_ERRORLOG="logs/error_log"
 -D AP_TYPES_CONFIG_FILE="conf/mime.types"
 -D SERVER_CONFIG_FILE="conf/httpd.conf"

mod_wsgi uses shared library version of python lib. python version 
is Python 2.6.2.  

the conf file details are --

LoadModule wsgi_module lib/mod_wsgi.so

LoadFile lib/libXXXX.so

WSGIRestrictStdout Off

    </Directory>

</FilesMatch>

</VirtualHost>

does mod_wsgi take longer than other modules to load or is there any way to 
improve the loadmodule time? Please help.
