Etherpad Scale Calculator

This page is designed to help you understand your hardware requirements for Deploying Etherpad at scale

The performance here is a rough guideline, we hope(not tested) over the coming months (by 2021) to have a roughly 5x improvement in performance.

We haven't tested Database performance with load across multiple nodes as of yet - We hope to have this research completed over the coming months

Input

Authors

An author is someone who writes at ~40wpm on a pad. This is a very active author. Most authors do not hit this average but we must account for it to handle edge cases. User productivity tends to drop with more than 3 concurrent authors on a pad

Lurkers

A lurker is someone who is recieving pad updates but doesn't contribute

Stability can be improved by increasing memory heap size availability if memory availability runs low

Each etherpad instance/node can currently handle ~10k msgs/sec
