# Use PGO?  Doubles the time and drive space requirements for the build,
# but should provide a performance increase.  How much depends on which
# benchmarks you believe, but I've typically seen around 2.5%.  I've also
# seen some which say it can be negligably (a fraction of a percent) slower
# with this enganged.  The anecdotal reports usually say there's a noticable
# improvement in overall responsiveness.  Seems like a good bet if you have
# the time and your system is able to handle it.  Set the variable to
# anything else prior to the build to compile Firefox in less time (but
# without the possible benefits of Profile-Guided Optimization).
#
# NOTE:  The 23.0 release fails to compile with a GLib assert error if PGO
# is enabled, so it is being disabled by default.  I can't say I ever noticed
# a lot of difference with this anyway (other than a much, much longer compile
# time.  But pass PGO=yes to the SlackBuild if you want to try it.
