I don't really consider it to be slow at all. It seems about as performant as any other language this complexity, and it's far faster than the 15 minute C++ and Scala build times I'd place in the same category.

The memory usage is quite large compared to C/C++ when compiling. I use Virtual Machines for Demos on my YouTube Channel and compiling something large in Rust requires 8GB+.

In C/C++ I don't even have to worry about it.

I can't say the same. Telling people to use `-j$(nproc)` in lieu of `-j` to avoid the wrath of the OOM-killer is a rite of passage

Why is the Rust compiler so slow?
