[mapguide-users] Performance Tips

[Andy Morsell]

I assume you are using the AJAX viewer.  Have you tried using Base layers at
all?  Once the tiles are created once, subsequent requests should be faster.
This would help speed up the server side of things.  For pure bandwidth
issues displaying the resultant image, you may want to look at changing your
map output format from PNG to GIF or JPG.  I know this can be done in one of
the web layout template files, but I honestly can't remember where.
Hopefully someone else who reads this can supply that information.

I'd be very interested to hear what people have found that have a big impact
on performance. After spending some time just working around problem after
problem to get an application ready for production, I now find that the app
may be just too slow in the clients environment to be of any use. I can
guess at a few like size of map, number of layers, complexity and format of
data sources. What is good practise? What can be tweaked to make things
faster? Can the image type (of the map) and resolution be changed? Is one
themed layer better than several filtered layers? I realise there are
hardware factors that will make a big difference, but I'd prefer to focus on
software configuration at this point.
