In practice 'quickly' is controlled by the settings on all the various 
network routers, switches and proxies handling the connection between 
client and server.
A database server may take 25 seconds to think about a complex query, 
but if one of the network switches handling the connection thinks 20 
seconds is an appropriate timeout, the response will never arrive.
