I've come back to starwind after some time with freenas, But this time the write performance is way worse then I remember. See the attached pic.
It could be because i'm using ReFS this time, that has a cluster size of 64KB where as the underlying storage is 4KB.
Update, changed it all over to NTFS and now I get this. Now it's like the RAM cache isn't used at all? except for ramdom reads.
Here are some pics of my settings.
This is with Write-Back turned on and 6GB of RAM.
