MRR tests measure the packet forwarding rate under -the maximum load offered by traffic generator over a set trial duration, -regardless of packet loss. Maximum load for specified Ethernet frame -size is set to the bi-directional link rate. - -In |csit-release| MRR test code has been updated with a configurable -burst MRR parameters: trial duration and number of trials in a single -burst. This enabled a new Burst MRR (BMRR) methodology for more precise -performance trending. - -Current parameters for BMRR tests: - -- Ethernet frame sizes: 64B (78B for IPv6), IMIX, 1518B, 9000B; all - quoted sizes include frame CRC, but exclude per frame transmission - overhead of 20B (preamble, inter frame gap). - -- Maximum load offered: 10GE, 25GE and 40GE link (sub-)rates depending on NIC - tested, with the actual packet rate depending on frame size, - transmission overhead and traffic generator NIC forwarding capacity. - - - For 10GE NICs the maximum packet rate load is 2* 14.88 Mpps for 64B, - a 10GE bi-directional link rate. - - For 25GE NICs the maximum packet rate load is 2* 18.75 Mpps for 64B, - a 25GE bi-directional link sub-rate limited by TG 25GE NIC used, - XXV710. - - For 40GE NICs the maximum packet rate load is 2* 18.75 Mpps for 64B, - a 40GE bi-directional link sub-rate limited by TG 40GE NIC used, - XL710. Packet rate for other tested frame sizes is limited by PCIe - Gen3 x8 bandwidth limitation of ~50Gbps. - -- Trial duration: 1 sec. - -- Number of trials per burst: 10. - -Similarly to NDR/PDR throughput tests, MRR test should be reporting -bi-directional link rate (or NIC rate, if lower) if tested VPP -configuration can handle the packet rate higher than bi-directional link -rate, e.g. large packet tests and/or multi-core tests. - -MRR tests are currently used for FD.io CSIT continuous performance -trending and for comparison between releases. Daily trending job tests -subset of frame sizes, focusing on 64B (78B for IPv6) for all tests and -IMIX for selected tests (vhost, memif). - -MRR-like measurements are being used to establish starting conditions -for experimental Probabilistic Loss Ratio Search (PLRsearch) used for -soak testing, aimed at verifying continuous system performance over an -extended period of time, hours, days, weeks, months. PLRsearch code is -currently in experimental phase in FD.io CSIT project. |
