AB Test ToolsAs part of the Apache HTTP Server project, AB is a relatively simple developed benchmark tool and is suitable for most environments where Apache is installed.It has a number of parameters, and we have a few tweaks to how it guides the test, with 3 parameters that are often used:1)-C #: The number of concurrent requests per second, o
