I am not an expert on input queues, but from my experience, the 256K
recommendation is based on 8 threads.. the goal is to give 32K to each
thread, so if you have 16 threads, you would want 512K. I do not know if
there is a good way to find out if more on top of 32K would be good..
32K/thread (my servers run 64threads) works well for me so far with 1
Gigabit and two 100Mbit interfaces on each server.
