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

[Michael Shishcu]

Hello, Adrian
add to your apache config the folowing:

ScriptAlias /fcgi-bin/ "path to your mapserver binary file"
<Location "/fcgi-bin">
    # The following line activates the fastCGI script to all files in
location
    SetHandler fcgid-script
    ...
</Location>
regards, michael
