Hi, I have an issue with data transfers.
I tried striped mirrors, 8 drive Z2, 5 drive Z1 and for some reason im unable to get passed 200MBps on read and write over 10Gb link. When its in RAM cache i get up to 500MB/s, but once it reads or writes to the drive its in region of 160-200Mb/s no mater the config and on top of that it uses like 70% of CPU where assigned 8cores / 16 threads on PROXMOX. Any help? I dont know what to try anymore. It should be getting 6-700MBps on read!

Using this as guide im not getting anywhere near those numbers.
Dell R720 PERC i310 mini mono IT mode.
