On my system I see this at boot after loading the ice module from

Its about 1GB for the mapped pages. I don't see any increase moment to
moment. I've started an iperf session to simulate some traffic, and I'll
leave this running to see if anything changes overnight.
Is there anything else that you can share about the traffic setup or
otherwise that I could look into? Your system seems to use ~2.5 x the
buffer size as mine, but that might just be a smaller number of CPUs.
Hopefully I'll get some more results overnight.
Thanks,
Jake
