Fractal Wrongness In A Programming Language
I have 800 arrays of about 5000 integers each that I need to combine into an array of about 4 million integers. I don't care about the order or anything, I just want one big array.
PHP had used 8 minutes of CPU time and 1.2GB of RAM when I shot it through the head.
Solution: Don't use PHP.

That's a lot of RAM. I wonder what it was doing with all of it.

What format are the arrays in? 800 flat files on disk?

They were PHP arrays. Already in memory.

Flat files on disk turned out to be an enormous improvement, by the way.

I did not expect Minx to use PHP in the first place. I thought you just coded it all in Python driven off some modern equivalent of CGI.

Yep, Minx is all in Python, based on CherryPy. This was at my day job, where we are transitioning to Python but some stuff is still in PHP.
