I also don’t understand this, the rust compiler hardly bothers me at all when I’m working. I feel like this is due to how bad it was early on and people just sticking to that narrative
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+.
Maybe something else is going on then. I've done builds of some large open source projects and most of the time they was maxing the cores (I was building j32) but memory usage was fine.
