## Flags

| Short | Long | Description |
|-------|-------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| -c | --concurrency | Specifies the number of workers per job. Allowed only in continuous mode |
| | --cv | Coefficient of variation. Accepted in continuous and concurrency estimation mode. Benchmark keeps running until standard deviation is below the specified number |
| -i | --isolation | Requests to run every benchmark in a separate Erlang VM for isolation purposes |
| -s | --samples | Number of samples to take. Defaults to 1 for timed mode, 3 for continuous and concurrency estimation |
| -d | --sample_duration | Sample duration, in milliseconds, for continuous and concurrency estimation modes |
| -l | --loop | Sample duration (iterations) for the timed mode. Engages timed mode when specified |
| | --max | Maximum number of workers allowed in the concurrency estimation mode |
| | --min | Starting number of workers in concurrency estimation mode |
| -pa | | Adds extra code path to the Erlang VM. Useful for benchmarking *.beam files on your filesystem |
| -r | --report | Requests `basic`, `extended` or `full` report. Defaults to `basic` when less than 10 samples are requested, and `extended` for 10 and more |
| -q | -squeeze | Engages concurrency estimation mode |
| -t | -threshold | Sets number of extra workers to try in concurrency estimation mode before concluding the test |
| -v | --verbose | Turns on verbose logging (VM statistics and performance of continuous jobs) |
| -w | --warmup | Warmup |
