Hi Bob,
My guess is something like it's single threaded, with each file dealt with in
order and requests being serviced by just one or two disks at a time. With
that being the case, an x4500 is essentially just running off 7200 rpm SATA
drives, which really is nothing special.
A quick summary of some of the figures, with times normalized for 3000 files:
Sun x2200, single 500GB sata: 6m25.15s
Sun v490, raidz1 zpool of 6x146 sas drives on a j4200: 2m46.29s
Sun X4500, 7 sets of mirrored 500Gb SATA: 3m0.83s
Sun x4540, (unknown pool - Jorgen, what are you running?): 4m7.13s
This new one from Scott Lawson is incredible (but technically quite
possible):
SPARC Enterprise M3000, single SAS mirror pair: 3m25.13s
