# Configuration Cheat Sheet # Configuration Cheat Sheet
This is a cheat sheet for Pleroma configuration file, any setting possible to configure should be listed here. This is a cheat sheet for Akkoma configuration file, any setting possible to configure should be listed here.
For OTP installations the configuration is typically stored in `/etc/pleroma/config.exs`. For OTP installations the configuration is typically stored in `/etc/akkoma/config.exs`.
For from source installations Pleroma configuration works by first importing the base config `config/config.exs`, then overriding it by the environment config `config/$MIX_ENV.exs` and then overriding it by user config `config/$MIX_ENV.secret.exs`. In from source installations you should always make the changes to the user config and NEVER to the base config to avoid breakages and merge conflicts. So for production you change/add configuration to `config/prod.secret.exs`. For from source installations Akkoma configuration works by first importing the base config `config/config.exs`, then overriding it by the environment config `config/$MIX_ENV.exs` and then overriding it by user config `config/$MIX_ENV.secret.exs`. In from source installations you should always make the changes to the user config and NEVER to the base config to avoid breakages and merge conflicts. So for production you change/add configuration to `config/prod.secret.exs`.
To add configuration to your config file, you can copy it from the base config. The latest version of it can be viewed [here](https://git.pleroma.social/pleroma/pleroma/blob/develop/config/config.exs). You can also use this file if you don't know how an option is supposed to be formatted. To add configuration to your config file, you can copy it from the base config.

# How to activate mediaproxy # How to activate mediaproxy
## Explanation ## Explanation
Without the `mediaproxy` function, Pleroma doesn't store any remote content like pictures, video etc. locally. So every time you open Pleroma, the content is loaded from the source server, from where the post is coming. This can result in slowly loading content or/and increased bandwidth usage on the source server.

# Optimizing the BEAM # Optimizing the BEAM
Pleroma is built upon the Erlang/OTP VM known as BEAM. The BEAM VM is highly optimized for latency, but this has drawbacks in environments without dedicated hardware. One of the tricks used by the BEAM VM is [busy waiting](https://en.wikipedia.org/wiki/Busy_waiting). This allows the application to pretend to be busy working so the OS kernel does not pause the application process and switch to another process waiting for the CPU to execute its workload. It does this by spinning for a period of time which inflates the apparent CPU usage of the application so it is immediately ready to execute another task. This can be observed with utilities like **top(1)** which will show consistently high CPU usage for the process. Switching between procesess is a rather expensive operation and also clears CPU caches further affecting latency and performance. The goal of busy waiting is to avoid this penalty.

This strategy is very successful in making a performant and responsive application, but is not desirable on Virtual Machines or hardware with few CPU cores. Pleroma instances are often deployed on the same server as the required PostgreSQL database which can lead to situations where the Pleroma application is holding the CPU in a busy-wait loop and as a result the database cannot process requests in a timely manner. The fewer CPUs available, the more this problem is exacerbated. The latency is further amplified by the OS being installed on a Virtual Machine as the Hypervisor uses CPU time-slicing to pause the entire OS and switch between other tasks.

More adventurous admins can be creative with CPU affinity (e.g., *taskset* for Linux and *cpuset* on FreeBSD) to pin processes to specific CPUs and eliminate much of this contention. The most important advice is to run as few processes as possible on your server to achieve the best performance. Even idle background processes can occasionally create [software interrupts](https://en.wikipedia.org/wiki/Interrupt) and take attention away from the executing process creating latency spikes and invalidation of the CPU caches as they must be cleared when switching between processes for security.

When PostgreSQL receives a query, it decides on a strategy for searching the requested data, this is called a query plan. The query planner has two modes: generic and custom. Generic makes a plan for all queries of the same shape, ignoring the parameters, which is then cached and reused. Custom, on the contrary, generates a unique query plan based on query parameters.

By default PostgreSQL has an algorithm to decide which mode is more efficient for particular query, however this algorithm has been observed to be wrong on some of the queries Pleroma sends, leading to serious performance loss. Therefore, it is recommended to disable generic mode.

Therefore, it is recommended to disable generic mode.
Pleroma already avoids generic query plans by default, however the method it uses is not the most efficient because it needs to be compatible with all supported PostgreSQL versions. For PostgreSQL 12 and higher additional performance can be gained by adding the following to Pleroma configuration: Akkoma already avoids generic query plans by default, however the method it uses is not the most efficient because it needs to be compatible with all supported PostgreSQL versions.
