[p4] Is a 1500 line protect table excessive?

[Dave Lewis]

We have had a few hundred lines without trouble.  It seems to me that
it is more sensitive to the wildcarding.  We had some lines like
//depot/foo/.../bar/..., and expanding these to perhaps 15 lines and
dropping the first ... increased performance hugely.  I believe (but
I'm not sure) that protection table lines get pre-processed into a
more efficient form.  In the case I mentioned above, in p4win clicking
on a path to expand it might take a minute. After expanding the
wildcard, it took a second.

Still, 1500 lines seems like a lot.  We also had some branch specs
with 5,000 lines.  They were slow to use, but only the admins used
them so that wasn't a problem.
