[Mapguide_dev] MapGuide RFC 11 - Stateless Http GETTILEIMAGE request

[Trevor Wekel]

Hi Jason,
 
I can add a message to the server log indicating when the cache has been
flushed.
 
MgMap generation can be costly if the FeatureSource and LayerDefinitions
have not been previously cached.  For large maps, I have seen initial
MgMap createtimes in the 1 to 2 second range.  If the
FeatureSource/LayerDefinition docs have been cached, the create time
will go down to roughly 0.2 seconds.
 
If you interested in calculating create times for your maps, take a look
at the response times for mapframe.php/jsp/aspx.  This is where the
MgMap is initially constructed by the ajax viewer.
 
Thanks,
Trevor

I like this proposal.
 
Will there be a message written to the server log when the map cache is
flushed?  I don't know if generating the MgMap objects is especially
costly, but on a site that has more than 10 tiled maps set up, it's
probably worth being able to see where some additional performance could
be squeezed out.
