Hi, zil.. That's an additional ZFS cache, right? Shouldn't it be slightly faster, even without additional caches? Ralf On 04/24/2016 06:49 PM, Robert Fantini wrote: > if those are not ssd drives, then adding a zil drive will most likely help. > > On Sat, Apr 23, 2016 at 2:15 PM, Ralf

Re: [PVE-User] Proxmox + ZFS: Performance issues

Hi, I think my SATA cables should be fine, as dumping from the raw block device yields to 100MiB/s. I even tried offlining one disk and then checked performance: Still bad. But I don't get the point. If SATA cables were broken, how can I get good performance on raw block devices? Nevertheless, I

Re: [PVE-User] Proxmox + ZFS: Performance issues

Perhaps irrelevant, but a colleague of mine recently solved a puzzling performance issue merely by replacing the existing SATA cables with new, properly-rated cables. Turns out, much like USB v1 vs USB v2, there's next to nothing distinguishing SATA I cables vs SATA II cables vs SATA III
