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 (5) Test tools: fio with io-depth=3D1, thread num is 32 and = block size is 64k or 1M (6) RAID configuration: RAID 5, stripe size is 1M 2. Test result: (1) write performance too bad: 20Mbytes/s throughput and 200 = random write IOPS (2) read performance is expected: 700Mbytes/s throughput and = 1500 random read IOPS I tested the same hardware configuration with CentOS linux and Linux's = write performance is 5 times better than FreeBSD. =20 Anyone encountered the same performance problem? Does the mfi driver = have performance issue or I should give up on FreeBSD? =20 Jason
