Why is Docker Slow on Windows? Fixing WSL 2 Filesystem Performance

  You have a powerful Windows machine, yet your Docker containers feel sluggish. Simple tasks like   npm install , compiling Go binaries, or watching for file changes in a React app take exponentially longer than they do on a native Linux machine or a MacBook. The frustration is real: you execute a command, hear your CPU fans spin up, but the terminal hangs. The bottleneck isn't your processor or RAM; it is almost certainly  disk I/O latency caused by the file system boundary . This guide explains strictly why this architectural bottleneck exists and provides the definitive workflow to achieve near-native Linux performance on Windows using WSL 2. The Root Cause: The OS Boundary and the 9P Protocol To solve the speed issue, you must understand the architecture of the Windows Subsystem for Linux 2 (WSL 2). WSL 2 runs a real Linux kernel inside a lightweight utility VM. It uses a virtual hard disk (VHDX) formatted with the  EXT4  file system. However, your Windows ...
