How to benchmark apache with delays?

Question

What is a good way to benchmark apache with a delay between requests from a unix command line? The only benchmark tool I know from the command line is ab and it doesn't support delays.

Answer 1

You could run ab through watch to delay the repeated access, but you're not going to be able to use the report summary for much.

watch -n 1 ab -n 3 http://serverfault.com/

Or run it through curl instead of ab

watch -n 0.4 curl http://serverfault.com/
