The QGate Performance is enabler for performance test execution. Key benefits:
- easy performance testing your python code (key parts - init, start, stop, return)
- measure only specific part of your code
- scalability without limits (e.g. from 1 to 1k executors)
- scalability in level of processes and threads (easy way, how to avoid GIL in python)
- sequences for execution and data bulk
- relation to graph generator
