Does anyone have any code that can be used to test the speed of running some code. From my research (Performance Tool capable of testing code for speed, Lightweight load & performance testing frameworks), it appears that people simply use tools to do this (JMeter, HPLoadRunner).
But, I am looking to see if there is a piece of code that can be embedded in the script to monitor the speed of executing the code.
For more detailed performance of code I would look into profilers. That way you can analyse which parts of the code took long.
Load-testing tools gives you a benchmark from the outside. It can help you with comparing speed of versions against each other, but not analyse code problems.
I would try a services like NewRelic which gives transactional insights. It follows all the method calls of the application and reports how long they took, just like profiler, but now embedded into the test or production environment. Run a load test against the environment and analyse the results.
If your application has a CLI under Unix, you can use
time yourapplication arg1 arg2
