Previous topic, we discussed about Magento 2 Performance Optimization,
in this topic, let me introduce Performance toolkit which test Magento 2 store. The toolkit is Jmeter
Installation Jmeter
jMeter:
– Go to http://jmeter.apache.org/download_jmeter.cgi and download jMeter in the Binary section (pay attention that Java 6 or later is required)

Plugins (only if you want to use additional reports (like graphs)):
– Go to http://jmeter-plugins.org/downloads/all/ and download JMeterPlugins-Standard and JMeterPlugins-Extras
– Unzip them to the appropriate ext directory of your jMeter instance.
– Additional reports can now be added via GUI.
Usage of jmeter
Before running the jMeter tests for the first time, you will need to first use bin/magento setup:performance:generate-fixtures command to generate the test data.

Example:
> cd /directory_of_jMeter/bin/
> jmeter -n -t /path_to_benchmark_file/benchmark.jmx -Jhost=magento2.dev -Jbase_path=/ -Jusers=100 -Jramp_period=300 -Jreport_save_path=./
Run via GUI
– Open the jMeter/bin directory and run jmeter.bat
– Click in menu File -> Open (Ctrl+O) and select file; or drag and drop benchmark.jmx file in the opened GUI.

After running via GUI you can see the result of working in the left panel. Choose the corresponding report.
After running the script via console report will be generated in the path that has been specified in <report_save_path>.
Threads
jMeter script consists of five threads. Setup thread and four user threads.
The percentage ratio between threads is as follows:
Browsing, adding items to the cart, and abandoning the cart (BrowsAddToCart suffix in reports) - 62%
Just browsing (BrowsAddToCart suffix in reports) - 30%
Browsing, adding items to the cart, and check out it as guest (GuestChkt suffix in reports) - 4%
Browsing, adding items to the cart, and checkout as a registered customer (CustomerChkt suffix in reports) - 4%
About reports:
