%lookup vs. chain

I'm just noticing that as I spin through some large files that I'm chaining
out a million times (actually more) to a control file to check a flag.  In
the initial subroutine I'm setting up an array that I could easily store
this flag in.  I'm wondering what the opinion is as far as performance-wise
which is more efficient, doing the %lookup() on the array or chain to the
file?

Thanks in advance.

Mike
