Do comments increase page weight

Hiya there! Your comments and the user who commented on same post, and every info relative to user, gets stored in the database behind the scenes. Now in the real world web apps, a system has like multiple databases. They even have multiple back-end structures in different Frameworks. Sites like AirBnB, Youtube etc., have adapted their back-end architecture with multiple frameworks serving the same needs: Request-Response cycle.

Now everytime a user posts a comment, your back-end architecture generates a HTTP POST method and send it to the controller(C in MVC), which Controller routes it to database and either updates the existing data or creates new rows in multiples databases at the same time and then serves you the success confirmation on screen for the user. This is one Request-Response cycle. More the requests , more workload your server has to perform, right? Thats something defo you need to plan ahead of time so that your app or server wont break. And every comment does increase workload on your servers as well databases behind the scenes , and it affects the performance of your application.
