WSL2 is awesome -- and now I realize it.

WSL2 is a Windows Box that allows you to use Linux on your Windows Box.

I have long thought that this is a virtual machine (guest OS) with Windows as the host OS -- well, I am not wrong.

So, I assumed that the guest OS would always be "dragged down" by the performance of the host OS -- which is also generally not wrong.

-----

But last year, the person in charge of commissioning the production contacted me and said, 'If you use WSL2, you can improve the performance of the Go language.

Despite our doubts, I actually used the system and confirmed the surprising improvement in performance.

"This is not a host/guest relationship"

I finally realized that.

I looked into it, and I was right.

Well, I think this alone is great, but I am happy that I can use "sudo apt install" etc. without changing the directory structure of the Windows environment.

I can do the content of the article on development on Linux as it is on Windows, and coding is no problem with the Windows vscode intact -- is this heaven?

I was able to do "sudo apt" and "wget" and install the linux version of java.

For researchers who can't get away from Word or PowerPoint, but still need to develop on Linux, this is the perfect environment.

So, well, what I'm trying to say is,

When IT engineers use the words 'guest', 'host', 'happy', 'heaven', and 'best', they are talking about the IT development environment.

"They are not talking about juicy story"

I want you to know that.
