People say WSL2 is better

Not me. For some things WSL2 is better than WSL1, but for a lot of things it is worse.

  • WSL2 will eat your memory (originally 80%, now reduced to 50%) because they have no disabled the Linux Kernel IO caching functionality.
  • WSL2's time is not synchronized, cause serious clock drift when you let Windows sleep.
