README

benchmark-query-engine runs the streaming PromQL engine benchmarks and captures peak memory utilisation of the benchmark process.

Each benchmark is run in a separate process to provide some kind of guarantee that the memory utilisation is not affected by other benchmarks.

An ingester is started in the benchmark-query-engine process (ie. not the benchmark process) to ensure the TSDB does not skew results.

Results from benchmark-query-engine can be summarised with benchstat, as well as compare.sh.

Usage:

  • go run .: run all benchmarks once and capture peak memory utilisation
  • go run . -list: print all available benchmarks
  • go run . -bench=abc: run all benchmarks with names matching regex abc
  • go run . -count=X: run all benchmarks X times
  • go run . -bench=abc -count=X: run all benchmarks with names matching regex abc X times
  • go run . -start-ingester: start ingester and wait (run no benchmarks)
  • go run . -use-existing-ingester=localhost:1234: use existing ingester started with -start-ingester to reduce startup time
