Performance analysis of a Tor-like onion routing implementation

TL;DR

This paper evaluates the performance of a Tor-like onion routing system in Tribler, providing a measurement methodology to identify bottlenecks and guide future optimizations within the Tribler ecosystem.

Contribution

It introduces a reproducible measurement procedure for profiling onion routing tunnels in Tribler, aiding performance improvements.

Findings

Identified throughput limitations in Tribler's onion routing implementation

Developed a measurement methodology for tunnel profiling

Integrated performance analysis into Tribler ecosystem

Abstract

The current onion routing implementation of Tribler works as expected but throttles the overall throughput of the Tribler system. This article discusses a measuring procedure to reproducibly profile the tunnel implementation so further optimizations of the tunnel community can be made. Our work has been integrated into the Tribler eco-system.
