Why is my Rust build so slow?

Here's my edit-compile-run cycle in dev configuration: https://streamable.com/az397y

I use Qt, boost, lots of templates.

- clang as a compiler

- mold as a linker

- PCH (easy with cmake)

- plugin architecture for the software ; plugins are dynamic libraries when developing (everything is linked statically for releases which take of course much longer to build with lto, etc.)

- building on Linux (it's seriously slower on Windows, when using the exact same compiler on the exact same SSD)

Disabling Windows Defender in your build directories can be a serious boost. NTFS is still slow, though.

You can also disable Windows Defender for the build process, for example disabling it for devenv.exe makes Visual Studio builds waaaaaay faster!

Qt Creator I believe? Not 100% sure.
