I believe if you don't set rescan it uses the default value - but
would have to check on that. I know there is a way to tell it to not
rescan.

What is your rescan set to for that dataset? That is probably what
is causing it.
I am not using rescan or recheckEvery so that's probably the problem
the dataset element I'm using is pasted below:

Hi,
Is there a way to tell the TDS NOT to look for new files to add to
an aggregated dataset? I have several aggregations set up that do
not change (no added or removed or modified files). Yesterday
after generating the aggregation cache, access the dataset was
quite quick; ~1 second to load the Data Access Form. However, when
I try to access those same datasets today it takes just as long as
it did to generate the aggregation cache in the first place (5
minutes).
It should be noted that these aggregations are subsets of files in
a directory that IS being updated. What I have done used a regExp
to separate a very large dataset into years. The 2008 and prior
aggregations will not have files added so I'm looking for a way to
stop the TDS from searching for new files to add to the
aggregation cache.
Thanks,
Dave
