[mapguide-users] Unmanaged Performance

There's a bug about it here http://trac.osgeo.org/mapguide/ticket/175

It's not just SHP files which are affected, SDF suffers as well

Because of this bug, I always avoid using directory datasources,
create an individual
featuresource per file.

It doesn't really matter so much with only a few files, but it slows
down exponentially
the more gets added. I work with some maps which are so complex that I
had to increase
the PHP memory from 64MB to 128MB just for the fusion viewer in MapGuide to work

As usual with performance, if it ain't broke don't fix! but if you are
seeing real heavy
disk I/O with unmanaged resources, switching to managed resources is
going to ease
the load.
