How to get current method name in apex?

Question

I have a very slow Visualforce page. In order to find out why, I am adding a lot of System.debug() calls to the various methods on the controller to get timestamps etc to see what is so slow. So far I have code like this

public Boolean methodUsedByVisualForce() {
    System.debug('Start methodUsedByVisualForce');
    //lots of potentially slow work here
    System.debug('End methodUsedByVisualForce');
}

However, instead of findind and typing the method name, I would love to just be able to quickly add code like:

String CurrentMethodName = //code to get current method name
System.debug('Start methodName');

Php has a __METHOD__ function that will return the current method. Does apex have something similar or a way to get that info?

I have don't lots of searching and reading, finding lots of solutions that are close, but not enough. For example I can get the current class name with this code:

String CurrentClassName = String.valueOf(this).substring(0,String.valueOf(this).indexOf(':'));

I can use this class and example to get on what edition of Saleforce, or if it is in a sandbox.

But what I want is the current method name. How would I do this?

If you take a closer look at the debug logs you will find something like the following lines:

11:39:33.337 (3337420923)|METHOD_ENTRY|[28]|01pd0000002ukZM|ClassName.methodName([Method Signature])
11:39:33.337 (3337420923)|METHOD_EXIT|[28]|01pd0000002ukZM|ClassName.methodName([Method Signature])

So the system already logs the method names and together with the timestamps also the duration of the execution.

I would suggest, that you use the Log Inspector to drill down and see, which operation does take so long.
