How critical is the frequency of requests to the server for site performance?

Question

Web development

We all know that the size of downloaded resources is very important for website performance: images, fonts, styles, scripts and other files. What about the frequency of http requests? For example, there are 4 dozen vector images (individual pictures, not icons that can be placed in a sprite). In total, they weigh no more than 500Kb. Will they win the performance race when they have only one file against them, but weighing twice as much? What articles would you recommend reading on this topic?

Answer 1

Static, until you have it in hundreds of kilorequests, does not affect your site at all

Sprites are made to speed up requests from the client , since a limited number of sockets are opened on the client for one tab
File size should be limited 64-128- 256kb, depending on their clients - zhprs is still a reality

In total, they weigh no more than 500Kb. Will they win the performance race when they have only one file against them, but weighing twice as much?

You need to optimize the display of something to the user. Those who sit on a thick Internet will leave you after 1-10 seconds.

Answer 2

Need to freeze. Resources are loaded in parallel, as needed to display.
Depends on the browser-server pair.
