I am dumping about 284MB...

Now here is what I did...

1. identical drives on the same Adaptec 29160 controller
2. Each drive is sliced and formatted the same
3. I ran 'tunefs -n enable'
4. Mounted drive 2 as /mntg


Then as root do this: # dump -C 32 -0Lf - /home | ( cd /mntg ; restore xf - ) DUMP: Date of this level 0 dump: Wed Apr 7 16:17:13 2004 DUMP: Date of last level 0 dump: the epoch DUMP: Dumping snapshot of /dev/da0s1g (/home) to standard output DUMP: mapping (Pass I) [regular files] DUMP: Cache 32 MB, blocksize = 65536 DUMP: mapping (Pass II) [directories] DUMP: estimated 282911 tape blocks. DUMP: dumping (Pass III) [directories] DUMP: dumping (Pass IV) [regular files] warning: ./.snap: File exists DUMP: DUMP: 283002 tape blocks DUMP: finished in 45 seconds, throughput 6288 KBytes/sec DUMP: DUMP IS DONE


..that seems a bit slow for SCSI....


So now I try the EXACT same thing on another identical machine with the same cards/drives/ram..et (these machines are clones)...but this one runs solaris....

# ufsdump -0f - /export/home | ( cd /mnt6 ; ufsrestore xf - )
  DUMP: Date of this level 0 dump: Wed Apr 07 16:18:57 2004
  DUMP: Date of last level 0 dump: the epoch
  DUMP: Dumping /dev/rdsk/c0t0d0s6 (cheyenne:/export/home) to standard output.
  DUMP: Mapping (Pass I) [regular files]
  DUMP: Mapping (Pass II) [directories]
  DUMP: Writing 32 Kilobyte records
  DUMP: Estimated 571042 blocks (278.83MB).
  DUMP: Dumping (Pass III) [directories]
  DUMP: Dumping (Pass IV) [regular files]
Warning: ./lost+found: File exists
  DUMP: 571006 blocks (278.81MB) on 1 volume at 22362 KB/sec
  DUMP: DUMP IS DONE


That speed seems more reasonable.


Is there any reason that the FreeBSD machine is so much slower?

- thanks :)
