Hi Chris,Here is filebench I did with and without SSD, compression on and off again 2009.06 Hope it helps.BTW. You may want to connect your disks to onboard SATA port and see if it helps. My experience shows ZFS doesn't like HW raid controllers with onboard cache. Interesting results. Seems like compression can help as much as SSD. Although both are helpless on small random writes. I'm afraid that what we need most with our exchange servers which are kind of M$ DB designed. Do you have specification for hardware you used for tests? May I ask you what kind of storage you use eventually for your production (if anything with zfs)? |
