We recently tested a Dell R530 with a Chelsio T580 card, under FreeBSD 10= =2E3, 11.0, -STABLE and -CURRENT, and Centos 7. Based on our research, including netmap-fwd and with the routing improvem= ents project (https://wiki.freebsd.org/ProjectsRoutingProposal),=20 we hoped for packets-per-second (pps) in the 5+ million range, or even hi= gher. Based on prior testing (http://marc.info/?t=3D140604252400002&r=3D1&w=3D2= ), we expected 3-4 Million to be easily obtainable. Unfortunately, our current results top out at no more than 1.5 M (64 byte= s length packets) with FreeBSD, and surprisingly around 3.2 M (128 bytes length packets) with Centos 7, and w= e are at a loss as to why. Server Description: Dell PowerEdge R530 with 2 Intel(R) Xeon(R) E5=C2=AD2695 CPU's, 18 cores = per cpu. Equipped with a Chelsio T-580-CR dual port in an 8x slot. ** Can this be a lack in support issue related to the R530's hardware? **= Any help appreciated!
