Since it is a web server we are talking about here, let&#x27;s assume it is the backend space :)<p>I guess the answer is obvious: it is nice, but might not worth the effort. 1.2 million requests&#x2F;s is pretty good, but in reality, you probably would still need 2-3 other hosts as a failsafe backups, let alone there are other factors, like memory constraint, in which case, less optimized solution might be just acceptable because it is sufficient. So under common usage cases, the need for scalability outweighs the urge to squash the maximum performance from a single machine.
