Doesn't seem fair to do this comparison, but, here it is.
Spacely's results on a Unixbench 4.1 run: Spacely is, again, 14x400/8M-ecache
w/ 16GB RAM and an SBUS UW SCSI controller (Fast-20 maybe tops).

FINAL SCORE 468.1
[root@pulsar unixbench-4.1.0]#
Yes, the E6500 takes a pretty good beating, against the state of the art
midrange server (not a bad showing for a 5 year old midrange server that only
takes three times as much power (the 2650 sucks a lot of power!)). But
Unixbench isn't the best multiprocessor benchmark out there. The 16
concurrent shell test tells an interesting story, with the E6500 at 244lpm
and the 2650 at 366. The E6500 holds its own in the extreme concurrency
point.
On disk read throughput:
E6500:
[root@spacely unixbench-4.1.0]# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 78 MB in 3.03 seconds = 25.75 MB/sec
[root@spacely unixbench-4.1.0]#
Dell 2650:
[root@pulsar unixbench-4.1.0]# hdparm -t /dev/sda
/dev/sda:
Timing buffered disk reads: 154 MB in 3.01 seconds = 51.14 MB/sec
[root@pulsar unixbench-4.1.0]#
Spacely's not shabby on disk, considering:
[root@localhost ~]# hdparm -t /dev/hda
/dev/hda:
Timing buffered disk reads: 70 MB in 3.02 seconds = 23.16 MB/sec
[root@localhost ~]#
What is localhost? My Dell Inspiron 600m laptop with an ATA100 Toshiba 60GB
drive, 4200 RPM.
