The purpose of caching is to store certain data, so that subsequent access to the data is served faster. Unless your test tool will clear the cache after each iteration of the virtual user, the caching mechanism will start to give artificially faster page load times. This will invalidate the results of your test

Caching can have negative impacts on performance as well if it is not optimally configured. If the focus of your test is the front end, you should test it with caching on and off to see the impact.

If caching is used then the response time of the requested URL will vary and the results are going to be incorrect as due to caching the requested page is returned by the server from the servers cache.
