packets per second routing tests: mismatch between switch (~4M pps) and netstat (~10M pps) scores

2017-09-15 Thread Caraballo-Vega, Jordan A. (GSFC-6062)[COMPUTER SCIENCE CORP]
Hi all, We are currently running udp 1500 bytes pps tests through a Dell PE R530 and two Chelsio T62100-LP-CR NICs acting as a router. At the switch we are seeing ~4M pps, while with "netstat -w1 -d -h" we are seeing ~10M pps or ~31k in the same test. Any idea of why scores are so different? It co

As a summarywe have a Dell R530 with a Chelsio T580 cardwith -CURRENT. In an attempt to reduce the time the system was taking to look for the cpus; we changed the BIOS setting to let the system have 8 visible cores and tested cxl* and vcxl* chelsio interfaces. Scores are still way lower than what

What is the status of the freebsd routing proposal within -stable and -current? Dell PE R530 passing 8.4M pps

Hi, Below are some "netstat -w1 -d -h" results of a Dell PE R530 system (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. Versions 12-CURRENT (nodebug), 11-STABLE, and FreeBSD Routing Proposal image (http://dev.bsdrp.net/benchs/nanobsd
