I've found an issue in heavily increased loading time when mod_wsgi loads
the application for the first time. This has started since since upgrading
from my old setup of CentOS 6, Python 2.7.5, Apache 2.2.15, and mod_wsgi
3.4 to my new setup of CentOS 7, Python 2.7.13, Apache 2.4.6, and mod_wsgi
4.5.13.
The change has caused the initial loading time of the application into
memory from ~5 seconds to ~1 minute. I have followed the "Checking Your
Installation" as much as I could, coming up with a blank as to what could
be causing this increase.
The mod_wsgi and Apache configuration is the same across both the older and
new setup, configured to use the worker mpm module running in daemon mode.
Please find the configuration of both the virtualhost file and the worker
configuration found in the main httpd.conf file below.
*httpd.conf*
<IfModule mpm_worker_module>
StartServers 16
MaxClients 250
MinSpareThreads 10
MaxSpareThreads 10
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule>
*virtualhost configuration*

WSGIApplicationGroup xxx.com
WSGIScriptReloading On

</Directory>
...
</VirtualHost>
Any help would be greatly appreciated and if anyone can point me in the
right direction as to how to debug this issue further I will gladly oblige
to the best of my ability!
