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. For detailed information about performance tuning, see here.
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.
bin/pulsar-perf produce my-topic
After the command is executed, the test data is continuously output on the Console.

You can press Ctrl+C to stop the Pulsar Perf. After the Pulsar Perf is stopped, the 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.

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 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:
Clone the HdrHistogram repository from GitHub to the local.
git clone https://github.com/HdrHistogram/HdrHistogram.git
Switch to the HdrHistogram folder.
cd HdrHistogram
Install the HdrHistogram Plotter.
mvn clean install -DskipTests
Transform the file generated by the Pulsar Perf.
./HistogramLogProcessor -i <hgrm file path that pulsar-perf generated> -o <output file>
You will get two output files. Upload the output file with the filename extension of .hgrm to the HdrHistogram Plotter.
Check the test result through the Graphical User Interface of the HdrHistogram Plotter, as shown blow.
