Question about MTU and hardware offloading

Hi All,

I have 3 hosts for virtual machine and 3 for NAS/iSCSI. I want to have separate interfaces for all of the hosts on is so subnet and the other interfaces for VM/MGMT.

My question is. Is having MTU settings for 10G SFP+ iSCSi or any 10G connection still relevant with HW offloading and whatnot? I feel like ever since I've changes MTU settings and whatnot everything has been a but "laggy/slow"? Using ubiquity for the switch not sure If that matters.

Should I keep the iSCSI with MTU 9000 on the switch and host? And just keep everything at default MTU for VM traffic or?

Thanks in advance
