Can't say, as I don't personally have a 11K+ message mbox handy that I
can run the test on. I just don't keep that much mail around of my own...
But it works okay on my 4K to 5K message mbox files, which are the largest
I have... Usually takes about 1 second per 1K messages, so about 4 seconds
for the 4K mbox, 5 seconds for the 5K mbox, etc. Of course, a bit slower
when the server is overly busy... I've had it take 10 or 12 seconds before...
I do have users with large mbox files (12K+) who have never complained,
but that doesn't mean much... I don't know which ones do body searches,
or how often they do them, etc. And not all users complain even when there
is a slowness or outright problem...
So, no scientific data... But no complaints here... Then again, I only have
a small number of users with mboxes that large... We discourage that kind of
