Oddly, I did this:

cvs update -r 1.1

time cvs update -r 1.2 file1
time cvs update -r 1.2 file2
time cvs update -r 1.2 file3

And all of them took 1s.
And if I did 'cvs update -r 1.1' to reset them, it would do it all over
again.

I don't remember the specific files I was working on. It was in the
ports tree, and I was copying the command that ports was using.

So it was some sort of 'cvs -d repository update -d -r 1.1 path/to/file'
command. And the final revisions might have been more 1.5 or something.

But I did find that if I ran it repeatedly, without the reset, the times
all dropped. Maybe it matters that the files were in different
directories. I don't really know.
