Re: MapServer 5.0.0 released!

I hope that you didn't take my comment as though I was questioning the
validity of the comment. I was really just curious because of my
performance issues. I'll throw together a test case, who should I send
it to, just the list?

I posted (actually double posted because I'm blind..grr..not really) a
second note about being able to turn of antialiasing for a layer. It
really the 5 layers I'm seeing such a drastic performance difference
with. These layers are not very nice polygons, they are pretty detailed
with a lot of curves. I'm no expert by any means so there is probably
more I can do to speed up these layers. I have already broke them up
into separate smaller shapefiles as well as index them. Thanks.

That's based on feedback we got from most people who tested the new AGG
rendering. In most cases the impact was minimal and I think we even
heard of some cases where performance was better.

However I think there may have been a few exceptions, and your case is
clearly one. I didn't work directly on the AGG rendering myself so I
cannot comment on what could result in this performance hit. I'll let
those who know that part better comment on that.

BTW, if you could share a small test case (data + mapfile) that
demonstrates the difference then that would increase your chances of
getting help.
