Comment (by teor):

 Here are the CI wallclock build time improvements, in minutes.

 || '''Release''' || '''Current Speed''' || '''PR Speed''' ||
 '''Improvement''' ||
 || 0.2.9 || 16 || 9 || 44% ||
 || 0.3.5 || 11 || 30 || 63% ||
 || 0.4.0 || 13 || 20 || 35% ||
 || 0.4.1 || 20 || 32 || 38% ||
 || master || 13 || 35 || 63% ||

 These times vary depending on server load, but they are clearly better.
