Why does apache benchmark work so fast?

Question

Software testing

I'm trying to test my site with apache benchmark. I execute the following command:

[email protected]:~# ab -c 10 -n 1000 -t 60 http://127.0.0.1:8082/

`-t 60` means, according to the documentation, that the test should take 60 seconds, but everything works out for me in about 15 seconds. Then the result is displayed. What am I doing wrong?

Concurrency Level:      10
Time taken for tests:   20.123 seconds
Complete requests:      50000
Failed requests:        40016

Answer 1

Maximum number of seconds to spend for benchmarking. This implies a -n 50000 internally.

Max != total duration of the test.

Read the descriptions of the options carefully.
