I don't know much about it, but AFAIK gold is supposed to be several times faster at linking in general, and when using it in combination with gcc+LTO the compiler actually offloads some of the LTO processing to the linker which is supposed to be more efficient. I've never tried it personally, but I just googled and found this mentioned on the GCC site: "As an added feature, LTO will take advantage of the plugin feature in gold. This allows the compiler to pick up object files that may have been stored in library archives. To use this feature, you must be using gold as the linker and enable the use of the plugin by compiling with gcc -fuse-linker-plugin. This will shift the responsibility of driving the final stages of compilation from collect2 to gold via the linker plugin." And in gentoo you can switch to gold as explained on the wiki: https://wiki.gentoo.org/wiki/Gold
