 Important parameters are:
 
- * `--step` is the number of virtual clients added on each iteration.
+ * `--step` is the number of virtual clients increased on each progress.
  * `--start-n-clients` is the initial number of virtual clients.
    Even if you specify `0`, initially one client is always generated.
  * `--end-n-clients` is the maximum number of virtual clients.
-   This tool repeats benchmark until the number of clients is reached to this limit.
+   Benchmark is performed progressively until the number of clients is reached to this limit.
  * `--duration` is the duration of each benchmark.
    This should be long enough to average out the result.
    `30` (seconds) seems good for my case.

  * `--default-host` is the host name of the target endpoint.
    If the given request pattern has its own `host`, this will be ignored.

  * `--output-path` is the path to the result file.

-And, there are more parameters:
-
- * `--wait` is the inverval of each request sent by a client.
-   `0.01` (seconds) means "send requests continuously".
- * `--mode` specifies the request mode of the tool.
-   You must specify `http` for now.
- * `--n-slow-requests` is the number of reported "slow requests".
-   Slow requests are reported after the benchmark.
-   It will help you to do debugging.
+   Statistics of all benchmarks is saved as a file at the location.
 
 Then you'll get the reference result of the Groonga.
 After that you should stop Groonga to release CPU and RAM resources.
