I'm sure it depends on lots of factors and our worlds probably don't even match. I intend to eventually plot the numbers I've collected over the years (mainly to have a baseline for ZFS tuning) but so far I haven't and just looked at the first and last ones: -------------------------------------------------------------- >>> Kernel build for ZOEY completed on Mon May 31 17:18:12 CEST 2010 -------------------------------------------------------------- real 10m42.935s user 8m16.834s sys 1m22.951s -------------------------------------------------------------- >>> World build completed on Mon May 31 18:38:59 CEST 2010 -------------------------------------------------------------- real 71m16.524s user 51m55.771s sys 12m24.944s # FreeBSD r500.local 10.0-CURRENT FreeBSD 10.0-CURRENT #543 r+b74c91e: Sun = Feb 3 17:17:03 CET 2013 fk@r500.local:/usr/obj/usr/src/sys/ZOEY amd64 -------------------------------------------------------------- >>> World build completed on Tue Feb 5 21:33:55 CET 2013 -------------------------------------------------------------- real 261m25.904s user 189m2.690s sys 22m46.777s # FreeBSD r500.local 10.0-CURRENT FreeBSD 10.0-CURRENT #547 r+21d959a: Sun = Feb 10 16:00:14 CET 2013 fk@r500.local:/usr/obj/usr/src/sys/ZOEY amd64 -------------------------------------------------------------- >>> Kernel build for ZOEY completed on Sun Feb 10 21:41:31 CET 2013 -------------------------------------------------------------- real 18m34.822s user 12m13.900s sys 2m14.028s fk@r500 ~ $expr 261 / 71 3 I agree that it "feels" worse, though. Disclaimer: These aren't "benchmark" results, I didn't create them in single-user mode and various relevant factors vary. I also didn't run the numbers through ministat and don't intend to either. > Was it in 2009 when I could compile world in a few minutes on my quad > core. The same machine takes now hours despite having more memory. I'm using a Core(TM)2 Duo CPU T5870 @ 2.00GHz and don't remember ever being able to compile world in a few minutes. The bottle neck on my system seems to be the puny 2 GB of RAM the linker has to share with ZFS. At least I can still buildworld without first attaching an USB stick for additional swap space which is necessary for Firefox ...
