The answer is "it depends". This is similar to asking "what is the optimal response time from a web page?", the answer depends very much on the location of the requestor (client), the resouce that is being requested (server), whether or not the resource links to other resources (page contain components from other page, or in DNS, CNAME), and the client application requirements (does web browser expect a certain response time? Does DNS client expect a certain response time?)
Even with that said, as a rule of thumb, if your DNS server is taking more than 2000ms (2 seconds) to respond, it is too long. In the examples given by this (very old) thread, some DNS lookup tools are impatient and would declare anything over 2000ms as "unreachable".
