- Run a benchmark with a custom header:

`wrk {{[-t|--threads]}} {{2}} {{[-c|--connections]}} {{5}} {{[-d|--duration]}} {{5s}} {{[-H|--header]}} "{{Host: example.com}}" "{{http://example.com/index.html}}"`

- Run a benchmark with a request timeout of `2` seconds:

`wrk {{[-t|--threads]}} {{2}} {{[-c|--connections]}} {{5}} {{[-d|--duration]}} {{5s}} --timeout {{2s}} "{{http://example.com/index.html}}"`
