Polyfill Service Perf Measurements

Get Started

Run this command to start the measurements:

mvn exec:java -pl polyfill-service-perf

Runner Configurations

Modify src/main/java/org/polyfillservice/perf/RunnerConfig to change the configurations for your own measurements.
Things you can change:

  • number of iterations to run to get the measurements
  • number of iterations to run for warming up jvm before getting the perf numbers
  • user agent strings to use
  • service configurations

Example Output
