# Are questions about performance on-topic?

I can see questions where somebody has designed code to be explicitly fast and needs another pair of eyeballs to validate the code.

But are questions that ask explicitly about how to get more performance on-topic?

In my opinion the implied question in all posts on this side should be: "What can be improved about this code?". The asker is free to specify that he's particularly interested in suggestions about the code's performance (the same way he'd be free to say he's particularly interested in getting rid of the repetition in the foobar method), but any aspect of the code (be it the overall design, the coding style, the names of the variables or the performance) should be fair game for the answers.
