Poor VMFS copy performance in ESXI on ML110 Gen10 with P408i-P

ML110 Gen10 with P408i-P and 64 GB memoery

Have setup  two SATA Disc-arrays, one RAID 1-array using two SSD and one RAID6 array using six 8 TB SATA discs . Have installed ESXi 7.0 U2 May 2021 on a SD-card. 

Copying VMFS-files to both arrays from external source is really slow, around 10 Mbit/s on a 1Gbit/s network. The source is not the bottelneck. Also copying files within the server is also slow.. 

Performance inside a VM is not slow.

Any tips?

Found out that the P408i firmware was old. I had version 3.00 and latest is 3.41. Efter upgrading I saw that the cache read/write ratio was 100/0 för the RAID6-array,. After changing the ratio to 50/50, the write speed went ballistic compared to before.
