What is a difference between WSL and WSL2?
Experience Level: Junior
Tags: WSL
Answer
The primary difference and reasons for updating the Windows Subsystem for Linux from WSL 1 to WSL 2 are to:
- increase file system performance,
- support full system call compatibility.
WSL 2 uses the latest and greatest in virtualization technology to run a Linux kernel inside of a lightweight utility virtual machine (VM). However, WSL 2 is not a traditional VM experience.
WSL 2 is a major overhaul of the underlying architecture and uses virtualization technology and a Linux kernel to enable new features.
