I look forward to a good result because many professional storage company use FreeBSD as its OS. But I am disappointed with the Bad performance. I tested the the performance of LSI MegaRAID 9260-8i and had the following bad result: > > 1. Test environment: > (1) OS: FreeBSD 10.0 release > (2) Memory: 16G > (3) RAID adapter: LSI MegaRAID 9260-8i > (4) Disks: 9 SAS hard drives (10000 rpm), performance is expected for each hard drive Were the drives completely initialized? I remember that at least one vendor had implemented read-past-write for every sector when written first. It was with 15k 3.5" spindles and I'm really not sure which vendor it was, so I won't name any. But "slow init" had solved a similir problem for me back then... -Harry _______________________________________________ [email protected] mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-hardware To unsubscribe, send any mail to "[email protected]"
