A couple of issues / tips we have found in this sort of scenario.
1) Edit your epsg file to contain only the projections you want - this
can make a big difference - presumably because its doind a slow string
search each time
2) If using OpenLayers (or google maps etc) - the tiling sends
multiple

I guess that wms makes a reprojection job as the request comes with an
EPSG code and the map projection is set by a proj string. Even if they
are equivalent, can MapServer know that and forget about reprojection ?
The cgi is rather straight forward as no EPSG is required. As the layers
don't have
Hi John,
Could you try to set your map projection with its EPSG code instead of
the proj string, and see what happens ?

Hi Paul and other MapServer Gurus,
I have discovered a huge speed increase by using OpenLayers.MapServer (native)
layers instead of OpenLayers.WMS layers. It is about ten times faster, I do not
exaggerate. Why is WMS so slow? I have read that MapServer is a fast WMS
server, have I done
Okay, maybe not ten times faster - but at least five times as fast - if not
more. Anyway, ALOT faster than WMS :)

John,
The idea that CGI is naturally a much slower situation than a
long-running process is a bit of a red herring in the case of

Hi,
I am trying to use fast_cgi with MapServer, specifically mod_fcgid on SLES 10.2.
I have mod_fcgid correctly set up within Apache because it works with another
FCGI application (IIPImage).
I have successfully compiled MapServer 5.2 with fast_cgi support. I used this
page to help me:
John,
The idea that CGI is naturally a much slower situation than a
long-running process is a bit of a red herring in the case of
Mapserver, and I say that as someone who is anal retentive about these
things. Unless your Mapserver installation has some naturally latent
components (database
Hi Paul,
Thanks for the useful information. The performance is pretty terrible, so I
will have to do some more investigating. The MapServer executable almost
completely maxes out two cores and it can take 30 seconds or more to fetch all
the tiles for a particular view. I do connect to Postgres
Pull out your command-line, you probably have a linking library
problem, and mapserv is just dying unceremoniously.
So first: can you just run mapserv on the command line. If not,
what's the error? is it instructive?
Second, if just a plain mapserv runs, what happens when you feed it
