Example of AB:
To execute the connection for 1000 times and concurrent for 20 times (in parallel ):

Syntax: AB-N 1000-C 20 http: // localhost/

Note the following:

§ Time taken for tests: total execution time (over 1000 times)

§ Requests per second: the average number of connections that can be processed per second.

The following is a test on the Windows azure virtual machine. The performance of the virtual machine is not good (compared with ASP. NET web API vs node. js benchmark, take 2 ).
