If it finds the edges that you think it should, then it's good.
Realize that what constitutes an edge is a judgment call.

If you want to measure the speed of the algorithm, use the profiler

If you have a 2-second egg timer and a 5-second egg timer, then you can
measure the performance of the program to within 1 second no matter how long
it runs.

Download Lena. It's the head and shoulders of a Playboy centrefold, and the standard test image for digital image processing algorithms.

Then compare how your algorithm does versus competitors. A Google search on "Lena" and "edge detection" turned up several hits, which should lead ypu to the metrics other people use.
