[mapserver-users] WMS Server Optimization?

[Andrea Peri]

I set always the EXTEND information at the layer level.

This speed really the startup of mapserver.
Without the EXTENT al layer level the WMS try to calculate it to respond at
a
GetCapability request.

I guess the wms_extents is not sufficient to speed up mapserver.

hope to help.

Andrea.
