I'm currently trying to load a 32MB trace file in the Service Trace Viewer tool, but performance is dreadful. At this pace it will take about half an hour to process. Something that I think should be prevented by partial loading. Microsoft says the following on the matter:
You do not need to manually enable partial loading. If the total size of the trace file(s) you attempt to load exceeds 40MB, Service Trace Viewer automatically displays a Partial Loading dialog for you to select the part that you want to load.
Is there really not a way to enable this for files smaller than 40MB?
