1 Time run is 114 ms, cpu 0.0% and memory318M 2 Time run is 98 ms, cpu 0.013651877133105802% and memory318M 3 Time run is 106 ms, cpu 0.007391130643228126% and memory318M Every 5 seconds measure end-to-end latency and the cpu and memory of some other process. Only need to open an nrepl to slightly increase the load, and write the results to some edn file I can start running benchmarks.
