It depends on the setup of your SAN/NAS.  If it's a Linux based distro you will definitely have to do some tuning on top of enabling jumbo frames.  Linux is great but it has to make conservative decisions to prevent bad stuff from happening.

what have you tweaked?

 

What os? Have you tried tifferent oses?

 

What exact iperf command are you testing? Have you tried multiple threads?

My SAN is FreeNAS and required all of 3 things to tweak, but the receiving side on my Proxmox host required some tweaking.  I can get the guide for you if you want.

As for fun benchmarks.  I've used crystal disk mark, and atto for IO benchmarks when I feel like seeing big numbers.  I also do everything over multi-node fiber.

All of my VMs get their iscsi storage served to them via LVM.

What exactly did you tweak?

 

What iperf speeds do you get? what settings?

 

WHats your network diagram?

 

What speeds do you get when you benchmark on the freenas system?

Problem identified:

bad / wrong NIC in Gaming PC. Im looking to fix it soon. If it doesnt help I have to buy a new / better one. My recent card is :https://www.asus.com/Networking/XG-C100F/ for 50€ on ebay used.

Maybe I will buy an Intel Card.
