See this existing trac ticket on this topic:
http://trac.osgeo.org/mapguide/ticket/175.  If you enable pooling for
SDF (I believe SDF by default is excluded from pooling in
serverconfig.ini) you should see the same performance increase noted in
the ticket.  The development team is aware of these issues and have set
the milestone for this to be fixed in release 1.3

Hi all,

I hope someone can point me in the right direction, I am using 1.2 and
have re-mapped data to a location on disk.  I am seeing a noticeable
difference in response time between managed and unmanaged data.  I
re-mapped my feature source as shown below.

Original
<?xml version="1.0" encoding="utf-8"?>
<FeatureSource xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xsi:noNamespaceSchemaLocation="FeatureSource-1.0.0.xsd">
  <Provider>OSGeo.SDF</Provider>
  <Parameter>
    <Name>File</Name>
    <Value>>%MG_DATA_FILE_PATH%AsBuiltBldgs.sdf</Value>
  </Parameter>
  <Parameter>
    <Name>ReadOnly</Name>
    <Value>TRUE</Value>
  </Parameter>
</FeatureSource>

Modified
<?xml version="1.0" encoding="utf-8"?>
<FeatureSource xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xsi:noNamespaceSchemaLocation="FeatureSource-1.0.0.xsd">
  <Provider>OSGeo.SDF</Provider>
  <Parameter>
    <Name>File</Name>
    <Value>E:/FME_Data/mgos/AsBuiltBldgs.sdf</Value>
  </Parameter>
  <Parameter>
    <Name>ReadOnly</Name>
    <Value>FALSE</Value>
  </Parameter>
</FeatureSource>

After re-mapping I added the following alias to the serverconfig.ini
file.

[UnmanagedDataMappings]
UnmanagedSdf = E:\FME_Data\mgos


I then used the EnumerateUnmanagedData API to get the following.  But I
am not sure what to do next.

  <?xml version="1.0" encoding="UTF-8"?> <UnmanagedDataList
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="UnmanagedDataList-1.0.0.xsd">
	<UnmanagedDataFile>
	
<UnmanagedDataId>[UnmanagedSdf]AsBuiltBldgs.sdf</UnmanagedDataId>
		<CreatedDate>2007-06-28T13:00:40Z</CreatedDate>
		<ModifiedDate>2007-06-28T13:00:40Z</ModifiedDate>
		<Size>563200</Size>
	</UnmanagedDataFile>
</UnmanagedDataList>

Am I on the right track for improved performance/response time or am I
completely off base.  Any suggestions are welcomed.

Thanks,

David
