About

This guide is about performance optimization of the Allegro for specific use cases.

High Level Allegro Setup

The Allegro has various different units that can be optimized. These units are:

  • I/O Threads: responsible for all packet I/O operations
  • Analyzer Threads: responsible for decoding
  • DB Threads: optional threads offloading memory intensive database operations, see DB mode

Generic Optimizations

Packet Processing: Bridge vs. Sink Mode

For configuration, please see: Global_settings#Packet_processing_mode

The bridge mode requires approximately 10 % more load on the I/O Threads
