-Benchmarking the performance of terminal emulators is tricky. There are tools such as https://github.com/alacritty/vtebench but as called out by the author it's not a good representation of the actual E2E experience, and the best way is to simply test specific use cases.
+# Performance Benchmark
 
-While I continue to look for more systematic approaches for benchmarking, here's a video looking at smooth scrolling in Neovim as a key use case TerminalOne optimizes for:
+## 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 target for benchmarking)
+- 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 - moer often than not they are created by the application layer not the language
