>>Don't you have partial compiles? Parallel compiling?

We do. Without it it it takes over 3 hours for a full project build. Normally if I change one line of code and hit "run" it takes ~10-15 minutes for the app to start, depending on which file I changed.

>>Upgrade your machine?

It's a 64 core/128 thread core Threadripper workstation with 256GB of ram, so not many upgrade options from that.

It's a huge C++ project, heavily templated, that's kinda normal. My previous 2 projects were also like this.
