that's comparing windows vs linux, and file operations in Windows are more expensive than in Linux, they will probably optimize windows more but it won't get close, here's a good read: microsoft/WSL#873 (comment)

Windows Defender moment, and #10037

As a linux user, I prefer Bun stick with Linux + WSL, Windows is a pain to support, takes time away from more important things, why bother when you have WSL

I'm obsessed, honestly 😂

Are you ok with using WSL or you need native windows support for some reason ?

Yes, I don't have a problem, but I would be more happy if the speed of both was close to each

If WSL will always be faster than native Windows due to Windows just being slow, and spending endless time supporting a slower native Windows takes valuable time away from more important features, would you prefer Bun stick with WSL or continue support for native Windows ?

Well, I prefer WSL if it is more than 2x faster

For me, using vscode with wsl and plugins uses a lot more resources ~4gb per project. I normally have multiple vscode projects opened so that's like 8-12gb in total and it will bog down my computer. vscode without wsl runs fine though.

Can you give this a try in Bun v1.1.12 and let us know if you're still seeing a large performance difference between WSL and Windows with bun install?

now it takes 5 second ( not same project, but its good )

390 packages installed [5.01s]

I think a 2x - 3x difference on Linux is close to what it is on macOS. I'm going to close this for now but if you feel like it's too slow let us know and we can reopen.
