[users@httpd] Interpreting Results for apache benchmarking tool
Hi All,
I am using apache as a streaming server. So will it be fine if I am using ab
tool for stress testing apache in this scenario.
Confusion is coming up as till now I have seen ab being used for testing
static html web pages. Please correct me if I am wrong.
Also can you point to any document which can help in understanding the
results from the ab tool specially the one in bold below, pardon my
ignorance as I am new to this.
ab -n 200 -c 200

The items in bold are:
*min mean[+/-sd] median max
*Min = Minimum
Mean = Average
[+/- sd] = differences from Standard Deviations
Median= it is half way thru all the numbers arranged in ascending
order. If you have 11 numbers, the it is the 6th number.
Max= maximum number
Hope this gives a starting point.
