Excerpt of article text...

I often find myself having to measure the speed of some piece of code. It could be a method, or a loop, but most of the time it is different algorithms I'm trying out within a method.

Why within a method? Because I can see the code of the other algorithm and compare it with what I am doing. Oldtimers might remember that the old REAL.studio IDE had the ability to split a code window (which I found very useful), but I'm not aware of the Xojo IDE being able to do that.

In any case, I have made myself a little system to easily measure speed and show the results in different ways. And I assumed that everyone else had done the same. So I was quite surprised to hear that this is not the case.

Xojo's Profiler

Of course, Xojo already has a profiler that can analyze the speed of your app—so why create your own speed measuring system? That's a fair question.

But while the profiler is very useful, it isn't ideal. For one thing, its use is limited. It won't work in sandboxed apps, or on iOS (which admittedly I haven't really used), or with the remote debugger.
