It would be interesting to recent, standard, untuned 'make world' and compare the times for different processors, I/O subsystems. This would give us a good idea of what platform is ideal as a compiling machine, etc. 2. Doesn't make use timestamps (updating killed with 'noatime') for compiling (ie. seeing what is changed)? 3. What does CFLAGS= -pipe do in the make.conf file? 4. Can we tweak the CFLAGS= -m486 for out CPU-class? 5. Can we specify -O2 instead of -O (ie. what order of performance increase be)? 6. What is NOCLEAN=true & NOPROFILE=true ? (I know what they will kinda do, but how will it affect resultant 'world') Any answers to these would be nice, Dan _____________________________________ Daniel J Blueman BSc Computation, UMIST, Manchester Email: blue@challenge.isvara.net Web: http://www.challenge.isvara.net/ To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
