The ApacheBench tool for load test
The ApacheBench tool (ab) can load test server by sending an random number of concurrent requests. Although ab was designed for testing Apache installations, it can be used to benchmark any HTTP server. Example: $ ab -n 100 http://your site name/ $ ab -n 100 -c 3 http://your site name/ Explain: -c : Indicates how many clients (people) will be hitting the site at the same time. This means "concurrency". -n : Indicates how many requests are going to be done to the site. The final argument is simply the host.
