These numbers are consistent with my experience using spinning disks and comparing to SSDs. Basically, the build is mostly CPU bound.
You could probably close most ofthe difference by using a ZFS filesystem for the build that had the ZIL synchronicity turned off. (Its latency sensitive operations that are doing the most to add to compilation time, I expect.) -- Garrett D'Amore On Jun 5, 2011, at 5:55 PM, "Bayard Bell" <[email protected]> wrote: > Long and short seems to be that the difference isn't so bad, it's just > proportionately more when doing an incremental build in the case where there > aren't any changes. > > full build (-FnCDlmprt): > > ZFS > > real 56:48.91 > user 6:00:35.76 > sys 58:53.77 > > real 56:44.43 > user 5:58:27.00 > sys 1:36:39.84 > > NFS > > real 1:07:19.96 > user 6:04:27.15 > sys 1:19:09.63 > > real 1:11:43.07 > user 6:11:43.47 > sys 1:21:22.65 > > incremental (-iFnCDlmprt): > > ZFS > > real 28:45.12 > user 1:38:04.47 > sys 17:05.66 > > real 29:09.10 > user 1:32:59.43 > sys 59:13.10 > > NFS > > real 39:33.68 > user 1:37:55.99 > sys 23:06.83 > > real 39:57.23 > user 1:33:09.83 > sys 22:46.34 > > > _______________________________________________ > oi-dev mailing list > [email protected] > http://openindiana.org/mailman/listinfo/oi-dev _______________________________________________ oi-dev mailing list [email protected] http://openindiana.org/mailman/listinfo/oi-dev
