Feedback and/or tips and tricks more than welcome.
We are trying to process huge amounts of small (64 bytes) pps through a
router. So far results have not been as we expected. We have tested
FreeBSD 10.3, 11.0, 11.0-STABLE, and 12.0-CURRENT with and without
netmap. Based on netmap documentation we were expecting about 5.0M pps;
alongside with the routing improvements from the freebsd routing
proposal a total of 12.0M.
Server Description:
Dell PowerEdge R530 with 2 Intel(R) Xeon(R) E52695 CPU's, 18 cores per
cpu. Equipped with a Chelsio T-580-CR dual port in an 8x slot.
BIOS tweaks:
Hyperthreading (or Logical Processors) is turned off.
Current results are shown below. Additional configurations can be given
upon request.
Test Environment:
5 clients and 5 servers - 4 Dell C6100 and 2 Dell R420; each one
equipped with 10G NICS (4 intel 8259X and 6 with mellanox connectx2).
Script that execute the following on each host.
#!/usr/local/bin/bash
# Iterate through ports and start tests
for ((i=1;i<=PORTS;i++)); do
PORT=$(($PORT+1))
iperf3 -c 172.16.2.$IP -u -b10000m -i 0 -N -l$PKT -t$TIME -P$STREAMS
-p$PORT &
#iperf3 -c 172.16.2.$IP -i0 -N -l$PKT -t$TIME -P$STREAMS -p$PORT &
