FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

NGINX tuning for best performance

Moved to git repository: https://github.com/denji/nginx-tuning

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.

Upgrading PostgreSQL in Windows

Upgrading PostgreSQL in Windows

The official documentation for PostgreSQL provides a guide to upgrading using pg_upgrade. However, it can be a bit like a treasure hunt with hidden traps. This gist will walk you through a clear and robust method for upgrading PostgreSQL on Windows, using the upgrade from version 14 to 16 as an example.

1. Install the New Version of PostgreSQL

Before you embark on the upgrade journey, make sure you have the new version installed. This is because the pg_upgrade utility used during the upgrade process belongs to the newer version.

To get started, visit the official download page, download the installer, and run it. A word of caution: do not overwrite the old installation, as you'll need its binaries and data for the upgrade.
