No, "acache" is specifically intended to be used for authoritative
servers. It doesn't improve anything for a caching (only) server.
But if your server is a multi-processor/core machine, 9.4.x (and
onward) is worth trying with enabling threads. Its better support for
threads will improve response time comparing with 9.3.
