Hi Kencana,

Have your turned on the various caches for FeatureService in
serverconfig.ini?  Here's a set of parameters I have used successfully
on a map with 90 SDF layers.

[FeatureServiceProperties]
CacheSize                          = 600
CacheTimeLimit                     = 86400
CacheTimerInterval                 = 3600
DataCacheSize                      = 100
DataConnectionPoolEnabled          = 1
DataConnectionPoolExcludedProviders= OSGeo.SHP
DataConnectionPoolSize             = 200
DataConnectionTimeout              = 600
DataConnectionTimerInterval        = 60 

Thanks,
Trevor

That's a lot of layers. As I said, consider making the layers not
visible in the legend because it seems like the viewer is requesting
legend bitmaps for each layer/theme even though there is no visible
legend.

Are you using filters on the layers, and if yes, how complex are they?

The map is really slow to repaint even when there are very few features
visible so it must be the queries to FDO that are taking very long
(which includes whatever MapGuide does per layer in order to set up the
FDO select command).

How many of the layers are selectable or have a tooltip?

Traian

Hi,

for your information that there are 72 layers used for the map. and I
didn't use any feature join at all.

Thanks
