understanding apache bench?

[jamie]

i have just been benchmarking some of my scripts and am not quite sure what is what. e.g.:

QUESTION 1:

ab -n 1000 -c 50 /mypage.php

what is the difference between the -n and the -c switch.

does it mean that each user is requesting 20 pages (1000 / 50)?
or that each user is requesting 1000 pages?

--
QUESTION 2:

these are the results for different parameters:

ab -n 1000 -c 50 /mypage.php = 70 requests p.s.

ab -n 10 -c 50 /mypage.php = 15 requests p.s.

why should the time be so much faster when more pages are being requested?

any help is really appreciated. many thanks!
