While auto is a compile time burden, it creates a lot of load during compilation of this benchmark.

My complete Ph.D., using ton of Eigen components plus other libraries was compiling in 10 seconds flat on a way older computer. This requires gigs of RAM plus a minute.

the long compile times are mostly because im instantiating every dense decomposition in the library in one translation unit, for several data types (f32, f64, f128, c32, c64, c128)
