David -

I am not sure that DTS uses compression (as a default). It is noticeable when 10,000+ 
records are transferred.
There is a good WROX book on DTS programming. You might want to review it. I have not 
timed it. Just my impression.

The easiest measure is a stopwatch. If you double the records, does the time double? 
If yes, probably no
compression. You should test with a 'doubles' ... sort of plotting a graph. If the 
time is less than double, then
it may have compression. Your Network Admin should have a tool. The generic name 
escapes me. I recall they are not
cheap.

If you know VB, you can tweak the DTS code.
