FWIW, it takes my *first* generation PPro 150 (from Digital) 2 hours and 34 minutes for a make world (-O2, -pipe) on a slow 5400RPM SCSI2 Seagate drive... > > Also, I don't think having /usr/src and /usr/obj on different drives > help unless they are both on small partitions and physically located > near the other places on the disk that get accessed during the build > (swap, root FS, etc.). > Actually, I got a bit better time by splitting up /usr/src and /usr/obj -> down to 2:18 from 2:35. But like you said, not much of an improvement. I'm sure a single kick-ass SCSI-3 would be significantly faster... -Mark ---------------------------------------------------------------------------- Mark Mayo mark@quickweb.com RingZero Comp. http://vinyl.quickweb.com/mark ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ GCS/O d- s+ a-- C++ UB+++$ P+ L- E--- W++ N+ K- w++(---) O- M- !V PS+ PE Y++ PGP+ t !5 X+ R- tv b++ DI+ D++ G+ e+(*) h--- r++ y+(+++) ---------------------------------------------------------------------------- "Typically, I don't use JAVA -- I think that strong typing is for weak minds (and lazy compiler/interpreter writers)." -- Terry Lambert
