Load Testing with AB … fake failed requests (length)

Question

To do some load testing, for my own curiosity, on my server I ran:

ab -kc 50 -t 200 http://localhost/index.php

This opens up 50 keep-alive

Answer 1

Nevermind. The "length failure" merely indicates that about half the time the length of the response was different.

Since the contents are dynamic, it's probably the session identifier or something like that.
