In general, jumbo frames on low latency gigabit only helps with very specific use cases, and then only increases throughput by less than 5%. On faster media (10Gbit and higher), then you start to see 10% or so increase on even low latency connections, and even more of an increase on long-haul, high-latency connections.
If you have a lot (10 or more) of simultaneous active connections to your NAS and it has a single 1Gbit link, then having all devices using jumbo frames might help contention for that one link a little.
I have 10Gbit backbone that my servers are connected to, but all regular devices (PC, etc.) just use 1Gbit, and I use jumbo frames on the 10Gbit, but only on the VLAN that stays completely at that speed. Still, if @sam_nazarko wants to put 10Gbit in the next gen Vero, I’d be willing to test it.
