Hi there !
I'm using a couple of Pi 3B+, most of then running PiOS but one of them running Fedora 33. On all the PiOS ones, a "wget" download is going up
to roughly 30 MB/s, which fits to my Internet downlink and is near the maximum interface speed of this box. But on the Fedora machine, the
exact same command gets stuck at a fraction of this, even though it's connected to the same switch as one of the PiOS machines.
The Fedora box doesn't have a high load or something else which might be
an obvious reason for this effect. It's acting as a DHCP and DNS server.
Is Fedora's network stack that bad? Maybe I'll try a newer kernel
version (currently 5.11.15 whereas 5.14.18 is available).

That assumes both are 3B+ (which has true gigabit ethernet) not 3B (which
has ethernet hung off USB 2 as mentioned in another post).

I'll admit I'm continually confused by all the different Pi models,
but I did try to check this and according to this the Pi 3B+'s
Ethernet is still connected via USB, it just uses its own "USB
channel" (which I assume means no onboard USB hub in-between).
