Are tuples more efficient than lists in Python?
...bsolutely does not mean the same operations happen at the C (and therefore cpu) level. Try creating a class ListLike with a __getitem__ that does something horribly slow, then disassemble x = ListLike((1, 2, 3, 4, 5)); y = x[2]. The bytecode will be more like the tuple example above than the list ex...

And, when using round or inverting matrices, etc., these bits can make a huge difference.

Note that Xdebug counts the CPU time spent by PHP ; when PHP is waiting for an answer from a Database (for instance), it is not working ; only waiting. So Xdebug will think the DB request doesn't take much time !
