There is a usual hosting. There is a project uploaded to it. Check on GTmetrics and see a similar picture:

enter image description here

Despite the minimum file size, normal total page weight and a small number of requests, the site loads in 4-8 seconds.

Now the question itself:

  1. Blocking, DNS Lookup, Connecting, Sending, Waiting, Recieving - I roughly understand what each definition means, but can you describe each process in more detail and why do some files have such a long waiting or blocking process (what is Blocking in general)?
  2. When moving hosting higher, the performance does not change much. What do you think about VPS, Cloud VPS or normal north? What to choose based on 2-3 sites on different domains with a small load? Will Waiting and Blocking disappear at the same time?
  3. What tools do you use to analyze sites for speed. Well, except for the banal, like "Google PageSpeed", the above mentioned "GTmetrics"?

Thanks for your experience!
