Wow, there really are differences in hardware Message-ID: MIME-Version: 1.0 Content-Type: TEXT/PLAIN; charset=US-ASCII Sender: owner-freebsd-current@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I figured that within reason, most mb's would have similar performance, but I was wrong. All boxes are P6-200's, 256MB RAM (all RAM is 60ns FP as far as I know). Box 1 is a SuperMicro P6DNE: Function Rate (MB/s) RMS time Min time Max time Copy: 60.7395 0.2704 0.2634 0.2832 Scale: 60.8640 0.2719 0.2629 0.3097 Add: 70.9688 0.3508 0.3382 0.3602 Triad: 71.1647 0.3494 0.3372 0.3565 Box 2 is a Digital Prioris HX6000 Function Rate (MB/s) RMS time Min time Max time Copy: 73.3551 0.2197 0.2181 0.2249 Scale: 74.6067 0.2164 0.2145 0.2182 Add: 81.0584 0.2974 0.2961 0.3002 Triad: 77.4268 0.3108 0.3100 0.3122 Box 3 is a Digital Prioris ZX6000 Function Rate (MB/s) RMS time Min time Max time Copy: 84.8807 0.2018 0.1885 0.2834 Scale: 97.5461 0.1661 0.1640 0.1720 Add: 111.6549 0.2179 0.2149 0.2247 Triad: 100.9468 0.2659 0.2377 0.4237 Box 3 uses 256bit interleaved memory, rather than whatever the "standard" is. I thought it was just a marketing gimmick, but it seems to really make a difference. Have to see if it helps on some worldstone's.
