I read on Dmitri's Redemption site that Exchange cache's items.restrict
calls, and that using this method too frequently can slow an exchange server
significantly.

I can't find any reference to this anywhere else... or any advice on when to
use restrict and when to use filter/find/find next.

I suspect that some code on a customers site (that I didn't write) is using
items.restrict as part of a search process which is used regularly on a large
(15000+ ) public contact folder - which in turn maybe slowing the system.

Does anyone have any comments on rules of thumb for using items.restrict so
as not to 'bring a server to its knees' (in Dmitri's words)
