I remember when I got CodeWarrior on my PowerMac 6100/60 and suddenly I could answer questions online about weird MacApp problems by making a temporary project with their code and compiling the whole of MacApp in 5 minutes.
Previously that had taken about 2 hours (Quadra with MPW), and I did clean builds only when absolutely necessary.
Truly painful was trying to write large programs in Apple (UCSD) Pascal on a 1 MHz 6502.
I made a meme and sent it to my even older coworker with two guys from the office looking pensive. Titled 'The Build Failed Saturday and Again Sunday Night'
