Server response time?

Question

Computer networks

Hello!
Who can prompt as it is possible to reduce response time of the server, directly for the user? And is it worth connecting a faster Internet or is it all directly in the server?
For example, is it possible to reduce the given server response time in the picture

Answer 1

check like this

And not through Yandex tools
(On the screenshots there are Firefox web developer tools, in chrome and safari there are similar ones)
If you want to understand why some resource loads slowly on your computer, then why the hell do you know how fast it was loaded by Yandex robots? Moreover, you will not immediately understand what exactly Yandex considers during the server response time. Either study the certificate, or just guess.
Blocked - this is not about the Internet at all, some kind of internal reason for the delayed connection, in the OS / browser.
DNS lookup - you can influence this if you find faster / closer DNS servers, or organize your own local caching resolver (for example, in the organization's network
)- basically there are delays due to a crookedly configured server, whose queue of incoming connections does not have time to process everyone, or a slow Internet
Slow installation of TLS - here fifty fifty, maybe your computer is slow, maybe the server (or maybe packets are lost somewhere between )
Sending - if there is a delay during the normal opening of the page, then there are big questions about the speed of your Internet (there may be a delay if you do not open the page, but upload the file to the server via a POST request) You cannot affect
the " wait " item at all, it's purely server side.
A faster Internet in modern realities significantly affects only the last stage in this data waltz - obtaining. And then under the conditions that the server can give back at the speed with which your Internet allows you to receive
If the total time of all timings is less than 300ms ( we don’t look at the Blocked item ), then we can conditionally assume that the site, in layman’s terms, is “fast”
