A curiosity happened in late September 2019. This was when I added the Ryzen 5 as the Snakeoil development server. The network between my NAS and the Ryzen are changed as such:
In an attempt to simplify my home setup. I have decided to purchase 2 dual port 10Gbps NIC - one for my NAS, and the other for the new Ryzen. These network cards will be connected at 10 Gbps to my main switch, and also a direct connection between the NAS and the server itself (dedicated iSCSI connection).
iSCSI is works like a SATA cable, but it’s connected via normal networking equipment rather than between your SSD and motherboard. Now for some reason that still eludes me, the iSCSI data just refuse to work properly with Jumbo Frames on.
So in an attempt to troubleshoot the problem, I have disabled Jumbo Frames throughout my entire network. Unfortunately with a MTU of 1500, the sound I get from my Hifi just do not sound right.

"In my next article, I will setup the minimum equipment you’ll need for a Jumbo Frame enabled network. The article will also detail the steps you need to take to enable Jumbo Frames, and some basic diagnostics to ensure everything is working."
Yes! I wait this article with an high interest, we are at the beginning of local network optimization. Do you have a look to http://fasterdata.es.net/network-tuning/udp-tuning/?
