@VF1 That's an interesting finding. I know that the code behind SparseArray generation is highly optimized which is why it often outperforms more obvious and direct solutions, at least in version 7. Have you tried compiling Position to C? I recall someone reporting that as being very fast.

@Mr.Wizard f2 is surprisingly much faster than the typical C solution, when compiled (on my computer).

| Jan 11, 2014 at 20:34 | comment | added | Mr.Wizard | @s0rce I use version 7 which seems to be faster than later versions in a number of cases of basic programming. But yes, I have found clock speed to correlate well with Mathematica performance and I run an unlocked i5-2500K CPU at 4.6 GHz. | |
