This is a dual PPro 200/512k, 256 meg RAM, /usr/src and /usr/obj on seperate 7200 RPM UW SCSI drives on an aic7880 controller. After the build: /dev/da3s1e on /usr/obj (ufs, asynchronous, NFS exported, local, noatime, nosuid, writes: sync 82 async 44465) /dev/da4s1e on /usr/src (ufs, asynchronous, NFS exported, local, noatime, nosuid, writes: sync 6 async 44600) mortis:/usr/src root% time nice +20 make -j6 buildworld .... 7111.969u 2208.024s 1:38:44.38 157.3% 1386+1422k 32924+4824io 5880pf+0w Could probably push it a bit faster with a higher -j (8 or 10), but I didn't. X was running at the time, along with Netscape, ~30 xterms, and a few other sundry thingymabobs. -- Matthew Fuller (MF4839) | fullermd@over-yonder.net Unix Systems Administrator | fullermd@futuresouth.com Specializing in FreeBSD | http://www.over-yonder.net/ FutureSouth Communications | ISPHelp ISP Consulting "The only reason I'm burning my candle at both ends, is because I haven't figured out how to light the middle yet" To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
