<div>Just to clarify, I'm not specifically looking for how Nginx performs, but rather how our site performs, being that its a dynamic, php site and relatively quiet during the summer time (i.e. a good time to test) so I'm looking for a tool recommendation to simulate load as well as how to best process that information.</div>
<div> </div>
<div>Thank you for the advise, I'll take a look at some of the tool recommendations.</div>
