Hello
size=3>Sasikumar.
There are many factors that can affect load time, and many
things to work around how much data is transferred, but what steps to take
really vary depending on the type of data you are serving up?
Are you aware that the MG Author has a method to let you
know 'how much' data is being transferred and a per layer basis as well as a
whole map?
after a map loads in Author, look to the lower left corner
of the application, you should see:
'####### bytes transferred'
This is telling you the amount of data being
d'loaded. You can even watch on a per layer basis if you hit 'Rebuild
Layer' it will show how much is being transferred for that particular
layer.
As to what can you do to improve performance:
- Don't have all layers turned
on for the initial map view
- Use visibility scale ranges to turn
on and off data
- Generalize the SDF's (limit the number
of vertices for particular scales - Create
different 'density' sdf's for different viewing scales
- Indexing columns key columns
in dbases
- Use OLEDB
NOT ODBC data sources when possible.
- If raster's are involved,
sub-sample the rasters
- Could look at 'Static' map
layers for certain data
Hope this helps

Hi,
I need a help in Optimizing the size of MWF layers.
I have a small application which has to load the MWF map
layers
dynamically from the MapGuide Map Server.
when i try with local network,
it loads very fast
and performance looks good, but when i load the same
map
through internet from a remote system it takes arround
4-5
minutes. I just want to know,
What are the factors may affect the time in
loading the map[dynamically]?
What are the possible methods for optimizing
the layers size?
Help needed a bit earlier.
Thanks in advance.
Regards
Sasikumar
