As to https://lwn.net/Articles/139884/ a too large NAPI weight can cause increased system load as a driver may turn off polling and return to interrupt-driven mode if the quota was not filled in the last polling cycle creating the need of more interrupts to be handled. This commit decreases the NAPI weight from 64 to 32. Furthermore this commit decreases the default TX/RX ring buffer sizes from 128/256 to 64/128 as the buffers will unlikely be filled with a throughput <= 100 Mbit/s. |
