I downloaded the eepro100 NAPI patch and tried it in my test setup (a
1GHz P-III configured as a 2-port bridge, 2.4.20-8 RH9 kernel). I see
e100-napi perform much better than eepro100, which is what I was
expecting.
e100-v3.0.0dev12-napi 93k packets/sec
eepro100-napi-020619 49k packets/sec
When doing a bidirectional test, the eepro100 driver locks up
completely, although it seems to survive with 128 byte packets (where
the event rate is less).
What's your test setup? How are you generating your test traffic? Do
your NIC cards share the same irq?
