[mapserver-users] Any ways to increase performance of Mapserver?

[Adrian Popa]

Hello again,

I've compiled mapserver with fast cgi support and I've installed fastcgi 
on my apache. All seems ok, but I'm not sure if mapserver runs as 
fastcgi! I followed the instructions from here: 
http://mapserver.org/optimization/fastcgi.html

Here's what I've added in the configuration:

in httpd.conf (Apache2):

LoadModule fastcgi_module modules/mod_fastcgi.so

...
<IfModule mod_fastcgi.c>
  AddHandler fastcgi-script .fcgi
  FastCgiIpcDir /tmp/fastcgi
  FastCgiConfig -initial-env PROJ_LIB=/usr/share/proj -initial-env 
LD_LIBRARY_PATH=/usr/lib:/usr/local/lib:/usr/local/pgsql/lib 
-appConnTimeout 60 -idle-timeout 60 -init-start-delay 1  -minProcesses 2 
-maxClassProcesses 30 -startDelay 5
</IfModule>


When httpd restarts, I get in the logs that fastcgi starts ok:
[Wed Oct 21 15:43:04 2009] [notice] FastCGI: process manager initialized 
(pid 12570)

I think I should somehow link mapserv to fastcgi - because I see no 
obvious connection. The script handler is only for .fcgi, but 
mapserver's compilation didn't generate any fcgi files... It seems to 
me, mapserver still runs as a cgi process. If I list the running 
processes when there are no queries to the webserver, there is no 
mapserv process. When I list the processes while doing queries, there 
are several mapserv processes running.

Thanks,
Adrian
