I'm quite stuck with a very annoying problem.
I got a share server based on OmniOS 151030. When I try to export several video files from DaVinci Resolve, each time a file needs to be created, it takes something like 10 seconds to create it with around 400Ko on it, and then Resolve fills it at several hundreads of MB/s. Only the file creation process is extremely low.
If I run AJA System Test, BlackMagic Design speed test, or do a simple copy of many files at the same time, I don't have this problem at all.
If I set my export folder on any other NAS system I got (Qnap, Synology or simple Windows share), I don't have this strange behavior at all.
I tested many ZFS parameters, like enabling/disable arc and l2arc, changing recordsize deactivate nbmand and nfs, etc., but I really don't know what can cause this.
FYI sync is disabled. In case of, I even tested with sync enable and an Optane 900p as ZIL device, but I got the same problem.
I also tried this on another OmniOS server (also in 151030, fitted with 96GB of memory and an Optane 900p as L2arc), and they have the exact same behavior.
This make me think of a parameters to set somewhere but I'm still searching for it.
Does anyone have an idea of what can cause this?
