NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.

HTTP Streaming (or Chunked vs Store & Forward)

The standard way of understanding the HTTP protocol is via the request reply pattern. Each HTTP transaction consists of a finitely bounded HTTP request and a finitely bounded HTTP response.

However it's also possible for both parts of an HTTP 1.1 transaction to stream their possibly infinitely bounded data. The advantages is that the sender can send data that is beyond the sender's memory limit, and the receiver can act on

Using LUA script for HAProxy backend selection

Principle / HAProxy features used

HAProxy can extract pieces of information known as samples. Samples can be fetched from various sources, for the use-case described herein extraction from HTTP request is required.
A sample may then pass through a number of operators known as converters. A converter consumes a sample and produces a new one.
HAProxy standard fetches/converters can be extended by writing own fetches/converters in LUA

SSH Telegram configuration

Bot creation

Open your app and search for @BotFather, or open this link: https://telegram.me/botfather.
Type /newbot
Name your new bot (this is the contact name, like "Bot My server")
Give it a unique Telegram name, ending with bot(like "my_server_bot")
Now, you should see a token: keep it safe!

FAQ on the xz-utils backdoor (CVE-2024-3094)

This is a living document. Everything in this document is made in good faith of being accurate, but like I just said; we don't yet know everything about what's going on.

Update: I've disabled comments as of 2025-01-26 to avoid everyone having notifications for something a year on if someone wants to suggest a correction. Folks are free to email to suggest corrections still, of course.
