Hello,
the problem I have right now with mapserver is how to display roads
that must be displayed from different layers in a mapfile,
but should have nice joining with each other. Problem is shown here

Desired situation
First if you have 2 layers for roads like highways.shp and
secondary.shp (for example) if you make one shape roads.shp file with
the a field type performance will actually improve.
You can see a great example how to render street data (openstreetmap
data in this case) here:
Hey,
thank You. I was thinking that pre-splitting large datasets would be a
good optimization
step as suggested here: http://mapserver.org/optimization/vector.html
Have to try and compare ;)

Yes http://mapserver.org/optimization/vector.html this is described
correctly but it's not your case because you are NOT filtering SOME of
the data you just read ALL the data from 2 layers. I sort if you use
ALL the data from that layer there is no point in splitting.

However, this simplyfied example is for 3 layers, actually there is
about 8 layers and some of them are showing up
a little bit later (not in that scale range). So I guess the best
would be to create separate shapes based on scale ranges, ie 1:5
to 1:24000 the map will
