static content, images, avi, etc. are cached by the reverse proxy.
when a request includes them, the reverse proxy will serve them such that the connection will not be forwarded to the web server.

There are many links/discussion on "reverse proxy offload static content"


You should analyze and determine what causes the load on your setup.

Your setup might be that the majority of your issue deals with the data exchange to the backend SQL server.

Use perfmon on the backend sql server to see whether it is the issue you need to address.

Without knowing what the servers serve up, often the first thing is to offload the static contents by placing a reverse proxy.

Then you would make sure there is no memory leakage in your apps.

perfmon is a free tool that you can use to monitor the memory, disk, process, workers,
Establish a base line, and then look at peak times.
