I can think of a few odd cases where a RAM disk could still make sense; e.g., an application built to flush / fsync files at a high rate, like an embeddable temp database that doesn't have an in-memory mode. Certainly most apps are better off leaving this to the OS buffers. For serving static files over HTTP--unless the system is seriously starved for memory or there's some wacky process that mushes up the cache very often--a RAM disk is nonsense.
