Hi Paul. Thanks for bringing the discussion over here. We haven't done
this exercise for a while and probably a good thing to recap and also
include latest ideas. Maybe this time I will collect all the details
together and make a document of it somewhere.
So we can fill out the full picture, can you post the snippets from
nginx to set it up as proxy to Apache/mod_wsgi, plus the Apache
configuration snippets for mod_wsgi in Apache as well. Also indicate
the MPM Apache is built for and current settings in Apache for
Timeout, KeepAlive, MaxKeepAliveRequests and KeepAliveTimeout, as we
as for the MPM used what you have for:
# prefork MPM
# StartServers: number of server processes to start
# MinSpareServers: minimum number of server processes which are kept spare
# MaxSpareServers: maximum number of server processes which are kept spare
# MaxClients: maximum number of server processes allowed to start
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule mpm_prefork_module>
StartServers 1
MinSpareServers 1
MaxSpareServers 10
MaxClients 150
MaxRequestsPerChild 0
</IfModule>
# worker MPM
# StartServers: initial number of server processes to start
# MaxClients: maximum number of simultaneous client connections
# MinSpareThreads: minimum number of worker threads which are kept spare
# MaxSpareThreads: maximum number of worker threads which are kept spare
# ThreadsPerChild: constant number of worker threads in each server process
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule mpm_worker_module>
StartServers 2
MaxClients 150
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule>
That will give us a good starting point.
