Showing some curiosity might help. When you learn to profile and dig deeper, you will be able to understand what's going on, troubleshoot it and find the bottleneck(s). I remember the kernel compiling in sub-10 seconds on Egenera's multi-million dollar quad-socket blade racks a decade ago. Given the computing power, memory speed, bus speed, SSD performance and code-size today, there's no material reason similar figures shouldn't be attainable today.
