@cyberjock - I'm continuing to research and attempt to increase performance before i pull the plug and go back to 8.3.1.
I have however learned allot along the way.
For instance as i re-read this thread. I now know why my zfs versioning is different. I didn't realize we switched to OpenZFS. I was so focused on the new plugin system that i didn't really pay much attention to anything under the hood.
Anyways - more testing and research, have shown me that my write speeds are pretty good. I get around 100-120 mb /sec write.
but my read speeds are where things fall off.. i'm still getting 60-90 mb/sec read. average around 80's.
Do you feel this is a lack of ram issue? is there anything you can think of to improve read performance?
I also note with the new OpenZFS, that lz4 compression was enabled by default? is that correct? can i just turn that off at will? will it help performance?
If something was written with compression on and i turn it off, will it decompress correctly?
Thanks for your time.
