#2> Most web servers TCP slow start algorithm starts by sending 10 TCP packets.
Of course big names that run CDNs have fancy custom stuff that directly puts data into mmaped regions for the network card to use, but generally, it's the OS handling TCP connections, and this means that the web server, a user space process, only interacts with the TCP connection through a streaming API. It can't issue individual TCP packets or ACK packets or anything. Raw socket access requires superuser privileges in unix.
Outside of that it's a great article. Didn't know about this particular trick :).

#3Interesting poat, but what I really liked is the layout, font, bottom tags section, link to dev.to, etc. Very cool!

"web server" can refer to the whole box, as opposed to the userspace software in particular, so it's not wrong per-se.

The statement makes sense if you take web server to mean a logical unit including the underlying kernel.

#6This is a really great breakdown of the TCP slow start algorithm. I always try to keep sites as lean as possible, but this was an aspect of TCP that I wasn't familiar with but will definitely be keeping it in mind in the future.

#7Is the dev.to version of this article under 14k I wonder?

Definitely not — i've added a warning to the article.

#10I'm getting 62 bytes over the network and 31.4 kilobytes uncompressed. This page has more content than most pages I visit that are megabytes in size. I wish there was an incentive to go back to smaller web pages in general.
