    The storage pool is containing the 6x6TB disks, and all volumes on the virtual disks are formatted with ReFS with 64KB Blocks.

The server will primarilly stores files between 6-10GB in size, that isnt IOPS intense.
Ive recently ran a series of performance tests, and realized that the storate pool was performing extremely poorly with Parity.
If im copying a 10GB file from a server within the same VLAN over SMB, the transfer rate is between 90-100MB/s
When copying the same file to one of the SSDs or one of the 6TB disk as a standalone disk (evicted from the pool) on the Hyper-V server, im then able to fully maxout the 1Gbit link between the servers
I believe i have tested all the settings, that im aware that could be changed to tune this - but i cant seem to find a solution.
Is Storage Spaces supposed to run this slow, when using parity?
Please help.
I didn't find the right solution from the Internet.
