This document summarizes a presentation about scaling FreeSWITCH performance. It discusses how FreeSWITCH uses an insanely threaded model with session threads for each call leg. It also discusses some performance tweaks like reducing logging levels and moving the SQLite database to tmpfs memory to avoid I/O bottlenecks. Migrating to a database like PostgreSQL or MySQL may eventually be needed to move the database workload elsewhere for better performance.
