Yet another reason to put a wrapper around you mapserv binary.
I have hundreds of layers and block GetCapabilities outright and return
a proper warning stating such.
Obviously, this is not a solution for everyone. Adding this, some
security traps and whatever else you need to your wrapper is
One could do this already without changing mapserver, just at the web server
config. It would be hard to control in mapserver when you’d want to do this.

Option: we could consider adding a mapfile directive to point to a
GetCapabilities file (oh disk), which can act as an early out (instead of
generating Capabilities XML on the fly). We would want to test how effective
this would be for larger mapfiles (i.e. reading mapfile vs. rendering

https://www.mapserver.org/ogc/wms_server.html but how much faster it is depends
on the data
Great advice, thank you Oskar.
Could you tell me how long it takes to load the WMS into qgis or GetCap with
that many layers?
I am also interested in what purpose you are using the WMS with this amount of
data. Could you share it? In my case it is daily Sentinel-1 imagery for the
whole world
Hello!
I have 3234 layers in a service and it works fine. also works fine with
10.000 layers
1 try the getcap in browser
2a if step 1 is success change network timeout in qgis
2b if step 1 does not work change timeouts on server and check mapserver

I would take QGIS out of the equation, as recent MapServer does not have
a layer limit, see my instructions to test the exact QGIS requests in
your browser
Hi,
funny, how you type twelve.
1200 are very much and I guess no one has tried this before.
So to your question: I would say yes.
I suggest to split it into several services / mapfiles. The
capability-xml ist very big I think and most clients will habe problems
with it. The usability is
Hi,
With that information we cannot really say. Can you get the GetCapabilities
document by making the request with a browser or with curl? Is QGIS happy with
500 layers? I suppose that the default request timeout of Apache http server
(do you use it?) is 60 seconds, have you tried to increase
Hello,
I have a mapfile which constist of 1200 layers. While loading to qgis error
"Failed to download capabilities:Download of capabilities failed: Connection"
is recived.
Does this happen becaues of quantitu of layers in mapfile? Is there any
workaround?
Best,
Marcin
