Server response time delay

The server response time is the period from sending the request to receiving the first bytes of information. The site page consists of dozens of files. A long server response to a request to download content slows down the site.

If the delay in processing the request is periodic, then the problem is high load. The current server resources are not enough to serve all users at peak load.

You can speed up the return of files in the following ways:

Use HTTP2.
To prevent the server from compressing the file every time before giving it to the user, use pre-gzip compression or caching of compressed files. So, once compressed text files will not require repeated processing, which will greatly save resources.
Reduce the size of headlines. Cookies are sent at every request. By reducing them, you will reduce the size of the data transmitted over the network.
Use a faster nGinx web server.
Check that service procedures like “Keep-Alive”, SSL handshakes, caching headers are configured correctly. Make sure that the connection to the server is established 1 time and does not reset after downloading each file.
