testing with the CLI (running from WSL prompt) the slowdown does not happen. Deploy is about 10 seconds for small change with CLI, more like a minute with the plugin.

Was planning on installing WSL next week and streamline our process a bit. I'll let you know if I see the same. I know there's some complaints of speed with WSL2 in general.

WSL2 seems faster than Windows for things that are happening all inside WSL.

The complaint is the windows to linux communication https://docs.microsoft.com/en-us/windows/wsl/compare-versions#exceptions-for-using-wsl-1-rather-than-wsl-2 first point suggests using WSL1 due to speed

My experience has been - if you're using NTFS for the files, WSL1 is faster. If using WSL for the files, WSL2 is faster.

on wsl2 i have moved a lot of files to Linux file system and it sped up like crazy

Yes, I've noticed even

npm install

runs much faster than it did on plain windows.
