Functions

func ExpectFuncToComplete

func ExpectFuncToComplete(f func(), runtimeThresholdInSeconds float64)

ONLY COMPILES ON LINUX most often you will want to wrap the code being tested (i.e., f()) in a for loop to get more sizeable readings. use this function over built-in benchmarker (https://onsi.github.io/ginkgo/#benchmark_tests) to measure time using the OS user-time specific to the executing thread. This _should_ help with noisy neighbors in ci/locally.

other things to note while benchmarking:

• I've noticed the google cloudbuild hardware matters a lot, using nonstandard hardware (e.g. `N1_HIGHCPU_8`) has helped improve reliability of benchmarks
• we could still explore running tests with nice and/or ionice
• could also further explore running the tests with docker flags --cpu-shares set
