Performance Benchmark

Methodology

  • Benchmark done via https://github.com/const-void/DOOM-fire-zig
  • All terminals are run with defaults immediately after clean installation without custom configurations
  • Benchmarking done on Ubuntu 22.04, 11th Gen Intel i9 3.50GHz, GeForce RTX 3080 Ti
  • For consistency, we start DOOM-fire-zig, let it for 15 seconds and capture the results

Here's a video looking at smooth scrolling in Neovim as a key use case TerminalOne optimizes for:

  • Scrolling through the same file with the same Neovim setup on the same PC (11th Gen Intel i9 3.50GHz + GeForce RTX 3080 Ti)
  • First half is WezTerm (No criticism intended! WezTerm is an awesome terminal. Using it for comparison since it's commonly raised as a reference point)
  • Second half is TerminalOne
  • This comparison is mainly to highlight that Javascript doesn't inherently create performance bottlenecks - more often than not they are created by the application layer not the language
