Performance testing data in Magento2

Profiles

You can adjust the amount of data you create using profiles (small, medium, large, and extra large). Profiles are located in the <magento_root>/setup/performance-toolkit/profiles/<ce|ee> directory.

For example, /var/www/html/magento2/setup/performance-toolkit/profiles/ce

bin/magento setup:perf:generate-fixtures <path-to-profile>

bin/magento setup:perf:generate-fixtures /var/www/html/magento2/setup/performance-toolkit/profiles/ce/small.xml
