I always thought the big benefit to recompiling was to allow the use of
the latest instructions and system services. If the charts presented by
the compiler developers are to be believed, recompiling can have
tremendous positive performance impacts, especially when transitioning
from one hardware generation to another. If they stop recompiling their
applications, and just carry things forward using a copy approach, then
their applications might begin to "slow down" (relatively speaking)
whenever their systems are upgraded.
