Hi all,
I'm evaluating new stacks but seems that I'm stuck with mapserver and mapcache
due to the input source of our maps, so I'm trying to improve the speed of the
mapserver/mapcache stack and what I cannot improve is the seed speed.
The -n and -p parameters seems to be useless.

Sebastiano,
Some though in my mind:
* –n 2 : do you really have 2'000 CPU on your WMS server? if not, it
could be worst than better, flooding your WMS server.
* what is the bottleneck? If WMS server is slow you can't make MapCache
faster, you should optimise WMS Server. Multi-domain can help,
Hi,
When you seed tiles from WMS the slowest component is usually the WMS server.
And what the WMS server is spending its time is usually rendering. And what
makes rendering slow is usually that you render too much, and sometimes that
WMS server gets the vector data too slow because the backend
My MapServer is on the same server as MapCache and my network is pretty fast.
I was just trying to experiment with the -n and -p value and checking the CPU
load and I didn't seen any difference, but now that I read the responses I'm
trying -n 6 and the CPU and the RAM is more in use now and seem
Hi,
You can see examples about how to debug and improve the rendering speed with
Mapserver in the presentation of Lars Schylberg
https://media.ccc.de/v/bucharest-271-mapserver-optimize-for-performance.
Your maps look pretty and I hope you will find some bottleneck layers so you
can make them f
Thanks, I'll take a look at it :),
What should be maxsize to seed? Before was 2084 with 8 8 metatiles now is 4096
with 16 16 metatiles
I found some of the problematic layers, some of them take 4 to 6 seconds in TAB
files, while the same layer in raster take 40ms, we just need to find another
We don't create the data, we rely on OS (ordnance survey) to supply us the maps
files and then we publish them in our service but I assume that probably we
will need to create some flow to improve it or download it in other format that
is faster.

In our OpenLayer.js we first call the maximum extent of the map: "maxExtent:
new OpenLayers.Bounds (X1, Y1, X2, Y2)," on.
After the layer definition follows "map.addLayers ([lyr1, layer3, layer4]);"
and "map.zoomToMaxExtent ();". In between, the variable for
"OpenLayers.Control.GetFeature" is defi
I used the the excellent instructions at
https://mapserver.org/installation/iis.html to setup MapServer on WIndows
Server 2019, IIS 10, FastCGI. It works, but it's not seeing my
environment variables. I don't usually run MapServer on Windows but in this
case it's a requirement. In previous IIS inst
