Assuming 10,000 hits per hour, that would be 167 hits per minute or roughly 20s per request. I would assume that every decent webserver can serve 1 hit/s without problems no matter the backend.

Of course, depending on the work you do to render a page, rendering the data for display can take a bit longer, so even if your webserver can serve 1 hit/s (likely, more), you may want to have more than one CPU processing requests, and you likely want to cache data wherever possible. But nothing of this would "require" NodeJS, as both, PHP and Perl can do the same.
