[mapguide-users] Unmanaged Performance

I haven't tried just pointing to a directory with unmanaged data, all of
my feature sources have been set up to point to individual SDF files.
Perhaps that's why I haven't run into problems? I have seen some
performance degradation accessing unmanaged data across network shares,
but I guess that's to be expected.

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
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
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
