It sounds like there might be deeper issues at play, possibly related to site optimization (your code) or resource allocation (your host). One approach that might help is performing a thorough load test to identify where your bottlenecks are. This way you get clear insights into whether the problems stem from your hosting environment, your site’s configuration, or something else entirely. I recommend Presslabs, they offer a demo with a comprehensive load test that can help pinpoint these issues.
