I'm trying to troubleshoot some performance issues and my software vendor keeps pointing me back at the fact I'm not using an SSD which is what they recommend.
I put this 8-drive Z-Raid 2 array together for video editing and I've not had an issue with it so far (knock on wood). The drives are MG07ACA14TE from Toshiba
But now that I've installed sample libraries for Logic Pro on it, I'm running into issues.
When switching instruments in logic, if its an instrument on the SSD, the load is instant.
On the ZFS volume, the good loads are either instant or 1-2 seconds of delay.
But some of these I am seeing take 30, 45 even almost 60 seconds to load..... which just doesn't make a whole lot of sense to me unless I'm missing something painfully obvious.
It looks like many of these .nkx files are either 1GB or 2GB in size, so it should be sequential reads... I'm pretty confused as to why it is choking.
This is:
8x MG07ACA14TE with 4KB sectors and 256MB Cache
Installed in a Thunderbay 8 enclosure over Thunderbolt 3
I'm running the latest ZFS 2.0 release build (as of an hour ago) on Mac OS Big Sur 11.0.1 on a 2019 MacBook Pro 16" with Intel i9 8-core 2.4GHz cpu and 32GB of ram.
Any ideas on what could be causing this thing to chug?
