+
+This document describes how to use the Pulsar Perf for performance testing. For detailed information about performance tuning, see [here](https://streamnative.io/whitepaper/taking-a-deep-dive-into-apache-pulsar-architecture-for-performance-tuning/).
+
+## Pulsar Perf
+
+The Pulsar Perf is a built-in performance test tool for Apache Pulsar. You can use the Pulsar Perf to test message writing or reading performance.
+
+### Produce messages
+
+This example shows how the Pulsar Perf produces messages with default options. For all configuration options available for the `pulsar-perf produce` command, see [configuration options](#configuration-options-for-pulsar-perf-produce).
+
+```
+bin/pulsar-perf produce my-topic
+```
+
+After the command is executed, the test data is continuously output on the Console.
+
+**Output**
+
+```

+
+From the above test data, you can get the throughput statistics and the write latency statistics. The aggregated statistics is printed when the Pulsar Perf is stopped. You can press **Ctrl**+**C** to stop the Pulsar Perf. After the Pulsar Perf is stopped, the [HdrHistogram](http://hdrhistogram.github.io/HdrHistogram/) formatted test result appears under your directory. The document looks like `perf-producer-1589370810837.hgrm`. You can also check the test result through [HdrHistogram Plotter](https://hdrhistogram.github.io/HdrHistogram/plotFiles.html).

+```
+
+From the output test data, you can get the throughput statistics and the end-to-end latency statistics. The aggregated statistics is printed after the Pulsar Perf is stopped. You can press **Ctrl**+**C** to stop the Pulsar Perf.
+
+#### Configuration options for `pulsar-perf consume`
+
+You can get all options by executing the `bin/pulsar-perf consume -h` command. Therefore, you can modify these options as required.

+| trust-cert-file | Set the path for the trusted TLS certificate file. | <empty string> |
+
+### Configurations
+
+By default, the Pulsar Perf uses `conf/client.conf` as the default configuration and uses `conf/log4j2.yaml` as the default Log4j configuration. If you want to connect to other Pulsar clusters, you can update the `brokerServiceUrl` in the client configuration.
+
+You can use the following commands to change the configuration file and the Log4j configuration file.
+
+```
+export PULSAR_CLIENT_CONF=<your-config-file>
+export PULSAR_LOG_CONF=<your-log-config-file>
+```
+
+In addition, you can use the following command to configure the JVM configuration through environment variables:
+
+```
+export PULSAR_EXTRA_OPTS='-Xms4g -Xmx4g -XX:MaxDirectMemorySize=4g'
+```
+
+## HdrHistogram Plotter
+
+The [HdrHistogram Plotter](https://hdrhistogram.github.io/HdrHistogram/plotFiles.html) is a visualization tool for checking Pulsar Perf test results, which makes it easier to observe the test results.
+
+To check test results through the HdrHistogram Plotter, follow these steps:
+
+1. Clone the HdrHistogram repository from GitHub to the local.
+
+ ```
+ git clone https://github.com/HdrHistogram/HdrHistogram.git
+ ```
+
+2. Switch to the HdrHistogram folder.
+
+ ```
+ cd HdrHistogram
+ ```
+3. Install DskipTests through Maven.
