Etherpad Scale Calculator 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 Results Total CPU Cores(not CPUs) required: Total RAM per Cores(not CPUs)[note this is wildly over spec'd as usually 1Gb ram per core is plenty] required: Total Concurrent Authors: Total Concurrent Lurkers: Total Required Bandwidth Mb/s: Total Required IP Addreseses: More info 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
