I made some stupid programs to benchmark ethernet bridges with MacIIs.
One of them just sends ethernet packets at the highest speed possible,
the other just receives and counts them.
With these I got 98-99 percent, meaning ~1.24MByte/s.
The NUBUS and MacII should have no troubles keeping this speed.
The bottleneck is usually the ethernet driver, not the hardware.
