I re-configured with --enable-debug (for everything), and did a
partial rebuild (re-compiling whatever needed to be recompiled after a
fresh pull, which did include a lots of stuff that goes into
Now linking libmergedlo.so with -fuse-ld=gold takes 1 min 40 s, of
which 14 s user, 13 s sys (which I guess means it was mainly I/O
bound, my machine has just 2 GB memory). With -fuse-ld=bfd it takes 3
min 15 s (59 s user, 5 s sys).
With all objects built with debugging information the difference would
presumably be much larger.
So using gold does indeed seem to be useful, but only for builds
including debugging information.
