I've stayed away from onboard stuff since it's had a reputation of being wonky in the past. The comments from the dmesg just say "impressive". Coincidentally enough I do have a Tyan 2865 based system configured w/gmirror on a pair of WD 74GB Raptors in a 6.0-RELEASE-p7 box sporting an Opteron 165. So the mainboard and HD's are the same as the dmesg poster. fwiw- a quick default bonnie. In the interest of readability I've omitted the first two lines of headings: Machine MB K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU K/sec %CPU / sec %CPU selway 100 67385 56.8 50437 11.4 84770 18.6 94018 100.0 1475079 100.0 77505.9 156 Which is better than I get from dual Opteron 200 systems w/10K SCSI drives and LSI 320-1/2x controllers (until you spawn a few instances simultaneously..;-) -- Best regards, Ken Gunderson Q: Because it reverses the logical flow of conversation. A: Why is putting a reply at the top of the message frowned upon?
