1900 req/sec What kind of requests? Typically dynamic content usually is well below 300 req/s per core and goes down fast on many factors (e.g. non-local database.) Most web frameworks are usually below the 300 req/s mark. Of course it is a very complex subject as there are many things to consider. Good cache management, CDN, SSI, and reverse cache come to mind. About databases, it can become a problem if you do writes on the same database as locking starts to show its dangerous tentacles.
