Using dd to read directly from the raw disk device could be another interesting test, to find out the maximum sequential read performance of the hardware under Solaris, eliminating all file system overhead: ptime dd if=/dev/rdsk/c0t0d0p0 of=/dev/null bs=64k count=10240 Would that come close to freebsd's 40Mb/sec with UFS? -- This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
