2020-04-28vlib: startup multi-arch variant configurationRay Kinsella1-1/+1
Support for startup node multi-arch variant selection through startup.conf. This is to facilitate unit, functional testing and benchmarking of non-default multi-arch variant node code path. Also added parameters to make test, to specific using multi-arch variants in unit testing.

2020-02-18vlib: calculate per-worker loops/second metricDave Barach1-1/+2
Use exponential smoothing. Each sample has a half-life of 1 second. reported_rate(t) = reported_rate(t-1) * K + rate(t)*(1-K) Sample every 20ms, i.e. 50 samples per second K = exp (-1.0/20.0); K = 0.95; Type: feature Signed-off-by: Dave Barach <dave@barachs.net> Change-Id: I9aea5dd5fecfaefffb78245316adb4bf62eb2bd4

2019-01-24perfmon plugin: 2-way parallel stat collectionDave Barach1-15/+0
As a FUD reduction measure, this patch implements 2-way parallel counter collection. Synthetic stat component counter pairs run at the same time. Running two counters (of any kind) at the same time naturally reduces the aggregate time required by an approximate factor-of-2, depending on whether an even or odd number of stats have been requested. I don't completely buy the argument that computing synthetic stats such as instructions-per-clock will be inaccurate if component counter values are collected sequentially. Given uniform traffic pattern, it must make no difference. As the collection interval increases, the difference between serial and parallel component counter collection will approach zero, see also the Central Limit theorem.
