Essentially you fixed it by leaving enough clues for Apache to guess, but that relies on Apache having to expend additional effort hunting for the correct information. Using ServerName specifies it explicitly and allows Apache to start quicker.

 

Note that many hosting providers rely on ServerName to hide the real hostname or to separate out the identity of the Apache server from the host name - so that Apache can be moved between different platforms and still retain its identity without being tied to the underlying operating system. That's really the reason why many services (pure-ftpd, postfix, squid, etc) have a feature to establish their own identity separate from the OS.
