Checking files should be quick. It sends a query and gets the response - no
changes.  I get over 5 files/second on dialup. Make sure Options -> Spider ->
Update hack = checked.  Also increase Options -> Limits -> Max connections to
10/sec

Dynamic sites are different, they report the file has changed even though it
hasn't. (usually just the html not images and other files)  Only solution
there is stop interrupting the download, pause it and resume later.

If it's downloading other files repeatedly, I've see that on 3.4x, try 3.32.
