[mapguide-users] 30 seconds delay after creating +/-100 CreateRuntimeMap calls

[Benoit Begin]

I do believe you are leaking 1 MgByteReader per call.

Here is the definition of the function call:

public virtual *MgByteReader* CreateRuntimeMap(MgResourceIdentifier
mapDefinition, string sessionId, int requestedFeatures, int
iconsPerScaleRange);

It returns a MgByteReader. I strongly recommend putting it in a variable and
calling Dispose() directly on it. Odds are you are holding on to a bunch of
MgByteReader and the delay is the time the garbage collector takes to
manually dispose those objects.

My second recommendation would be to maybe not use CreateRuntimeMap. You are
not using the returned map definition whatsoever. You may as well just
create an MgMap and MgSelection directly and avoid some unecessary
processing? CreateRuntimeMap is useful when you want to have more
information about the map, including having Base64 icons for layers for a
legend type control. It doesn't look like this is the case for you.

Cheers,
Ben
