As illustrated by the growth of GCC itself. My bootstrap plus testsuite
run times on constant hardware have gone from under one hour a bit over
three years ago to over three hours now (and this is artificially low
because of the temporary disabling of Ada). Much of this is the growth in
GCC itself, but a significant part must be GCC slowing down.
By way of comparison with software where more attention has been paid to
improving performance, look at the Mozilla 1.7 release notes
<http://www.mozilla.org/releases/mozilla1.7/README.html>: "When compared
to Mozilla 1.6, Mozilla 1.7 is 7% faster at startup, is 8% faster to open
a window, has 9% faster page loading, and is 5% smaller in binary size.".
Previous Mozilla releases have also improved performance - despite new
features being added.
