After compiling binutils with "--enable-gold --enable-plugins" (ld.gold

Just a note, GCC doesn't need "--enable-gold" passed during configure. GCC
shares its top level configure script with other GNU projects, such as
binutils. When people build toolchains with binutils, gmp, mpfr, mpc and
many others in GCC's source tree, then it'd be needed.
When configuring binutils and using "--enable-gold=yes --enable-plugins"
then ld.bfd is the default with ld, and then there is ld.gold.
I'd be interested in some statistics. Is there are difference in size or
speed of applications that use this technology? I'd like to see some
quantification of the results.
My initial reaction is that using this would be fairly invasive for BLFS.
How many packages would need to be changed?
On the other hand, there are a lot of small packages where it wouldn't
make any difference. For example, would it make a difference for
something like firefox? I dowbt it would make a difference for something
like xfce for speed purposes as I can detect no delay in an function now.
