I'm thinking Wordpress, or bespoke status pages for internal apps. Of course you can get a PHP page out in under a millisecond if you try hard enough, but it's often not used in that sort of place. (And it often is, but that still doesn't mean it often isn't.)

Rails, for that matter, is known for being easy to produce multi-second pages too.

Slow languages are slow in practice, too.

It actually amazes me that people find the statement that slow languages are actually slow offensive and worthy of downvoting. As I said, it is my experience that simply switching from slow to fast languages even on "IO dominated" workloads has real, visible effects.

If you haven't tried it, consider trying it before becoming offended at the idea that your tool may not be appropriate for all use cases. Yes, it can matter when your language is 50 times slower than another.
