And any time you increase latency, that will have a negative impact on
NFS performance. NFS RPCs are usually small messages (except Write requests
and Read replies) and the RTT for these (mostly small, bidirectional)
messages can have a significant impact on NFS perf.

I still have some tool coding to do with PMC before I even think about
tinkering with this as I'd like to measure stuff like per-packet latency as

One quick note here. Every time you increase batching you may increase
bandwidth
but you will also increase per packet latency for the last packet in a

The great netmap generates only one IP flow (same src/dst IP and same
src/dst port).
