When addressing website performance issues, developers typically jump to conclusions, focusing on the perceived causes rather than uncovering the real causes through research.

Q&A
Q: Are there any specific tools that we can use to load test APIs?
A: Google PageSpeed Insights works only for public facing stuff. YSlow as a browser plugin will work on any page including authenticated, unauthenticated, or public facing so that might be a good choice.
Q: What is a normal/acceptable request per second (RPS) for a CMS site?
A: The acceptable number really depends on the hardware. From my experience with working with DotNetNuke content management system on an Azure A1 server, we start to see failures at about 102 - 105 requests per second. However, it really varies and will depend on what your application is doing (number of requests, number of static files it has, etc.). While there's not necessarily a gold standard, if you see anything under 100, it's typically a sign of an application configuration or other issue rather than the fact that you do not have a large enough hardware.
