how long does a make buildworld normally take? Has make buildworld time constant over the years? In 1995 "make world" on a Pentium Pro about 18 hours On my 4GB, CPU: AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ (1995.64-MHz 686-class CPU) make buildworld took about 18 hours. Well that CPU isn't the latest either (10 Years or so) Reminds me of a joke, saying that all bycycles weight the same (10lbs). Light carbon fiber bike 3lbs. need 7 lbs. lock Heavy steel bike 7lbs. need 3 lbs. lock As hardware grew faster over the years, software exploded the same way and eats up resources. Anyway, how could one speed up the make buildworld process? Parallelizing (make -j 8 or sth.)? I will try next on my 16GB notebook with i7-4720 (8core) CPU 1TB SSD and see what it gives. -- Christoph
