cvs update with file list is very slow

[Jason Elbaum]

I often invoke cvs using automatic scripts, and I've noticed that while
most cvs functions are very efficient, one scenario is invariably slow.
When I run "cvs update" with a list of files - sometimes a long list -
cvs seems to take a good second of time to process each file. "cvs
update" with no file list proceeds quickly through all the files in the
hierarchy.

Is this a known problem? Is there a way around it?

Thanks,
