I have found through trial and error that large data compares are very slow to complete, even if they are identical. My testing shows that upto 32768 rows displays the right side within 10 seconds and completes within 16 seconds. However, with 32769 or greater rows the right side displays within 15 seconds and the compare completes around 1 minute 35 seconds. In all cases I had 26 columns. If one of the csv files has 32768 or less and one greater, then the compare completes somewhere around 1 minute.
