IME, running older Asterisk versions seemed to benefit significantly from faster clocks,
particularly if you were dealing with physical DAHDI hardware. Disabling hyper-threading
can also bring some benefit. Exceptions include when compiling with "make -jX" where X
equals number of CPU cores, as well as when you are running other processes on the box,
or if your system is never transcoding and always allowing direct media between SIP endpoints.
