And have a look at "systat mbuf" and the values of LIVELOCKS and the per
interface ALIVE and CWM counters.
If the LIVELOCKS counter increases often or the CWM is very low then this
could explain the traffic issues since the interfaces will drop a small
amount of packets and this will cause a larger traffic drop on long
distance TCP sessions.
On the two main interfaces I see:
em0: 24 livelocks, 2k size, 29 alive, 4 LWM, 256 HWM, 29 CWM
em1: 42 livelocks, 2k size, 23 alive, 4 LWM, 256 HWM, 23 CWM
I've read a little about livelocks, to the extent that these look like
decently low numbers, but I'm afraid I have no idea what CWM is or what
a too-low number might be...
Thanks,
