color=#0000ff size=2>I have tried base layers before and will have another look
at them. I guess there is some trade-off in that with a non-tiled map, you can
zoom to the exact location you wish to in one go, whereas with the tiled option
you may need several clicks to zoom/pan to where you want to be. Overall it
should be faster though.</FONT></SPAN></DIV>

color=#0000ff size=2>Regarding image format, I think the template file is the
ajaxmappane.templ. I've tried using GIFs (which seem to give similar quality /
performance) and JPGs which produce a substandard map - unless there is another
parameter that can be fed to the mapagent, or perhaps something more than simply
'JPG' to the FORMAT parameter, to control the quality?</FONT></SPAN></DIV>

color=#0000ff size=2>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.</FONT></SPAN></DIV>

<P><FONT face=Arial size=2>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.</FONT></P>
