The lack of jumbo frame support does mean that the hardware does spam you with quite a few interrupts, but an upgrade to the driver to support the max hardware frame size probably won't require too much plumbing.W.

This means that a USB-attached SSD and the network connection won't be fighting over bandwidth. That alone should make a significant performance boost in any number of use cases.
So...additional congratulations to the chip designers for that feature.
This is FANTASTIC news! I can finally net boot or NFS mount all/parts of a retro gaming system and not have the USB issues I had before. Netbooting and NFS mounting game systems is just SO much better than having to worry about SDcard sizes, speeds, etc. Plus netboot makes it possible to have a single system be either multiboot or gming and desktop in one OS
I plan to try a KVM setup with a pretty bare SO that can run and actual OS as a VM as an alternative to multiboot with HDD images over ISCSI/NFS mounts once I can get a Pi4 4GB model.
