Profile tool to identify slow areas of a code on AEM server side

We need to identify which code taking more time during page rendering. To do that we need to use profiling which can show the timings of operations execution (code which is called in models and beans). We tried to use built-in profiler http://localhost:4503/system/console/profiler, but it is too simple, just collects stack traces of running threads without any other information like time of execution, etc. Due to this, we need a full-fledged profiling tool to measuring the time of code execution during page rendering.
We are using AEM 6.1. Are there any other built-in profiling tools or which profile tool can we use to achieve our goal?
