Zed vs Sublime Text Performance Matrix & Benchmark

Q: Why is Zed so fast compared to VS Code?

Zed is written in native Rust and renders text entirely via the GPU using Metal and Vulkan shaders, eliminating the Electron and Chromium DOM overhead.

Compare memory footprint, startup time, GPU rendering, and extension ecosystems between Zed (Rust) and Sublime Text (C++).
