Thanks for the detailed information. When you get the patch, I'd love to hear if it fixes the problems you're having. From my understanding, a working prefetch would keep video playback from stuttering whenever the drive head moves — is this right?
The inability to read and write simultaneously (within reason) would be frustrating for a shared video editing server. I wonder if ZFS needs more parallelism? If any software RAID ends up having a similar problem, then we might have to go with the hardware RAID setups I'm trying to avoid. I wonder if there's any way to work around that. Would a bigger write cache help? Or adding an SSD for the cache (ZFS Intent Log)? would Linux software RAID be any better? Assuming they fix the prefetch performance issues you talked about, do you think ZFS would be able to keep up with uncompressed 1080p HD or 2K? -- This message posted from opensolaris.org _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
