mold is an easy win, with the following native file:

 1[binaries]
 2c_ld = 'mold'
 3cpp_ld = 'mold'
 4fortran_ld = 'mold'
 5[built-in options]
 6# mold 1.11.0 or later needed due to https://github.com/rui314/mold/issues/1017
 7# --no-as-needed temporarily necessary due to the seeming return of https://github.com/rui314/mold/issues/1017
 8c_link_args = ['-fuse-ld=mold', '-Wl,--no-as-needed']
 9cpp_link_args = ['-fuse-ld=mold', '-Wl,--no-as-needed']
10fortran_link_args = ['-fuse-ld=mold', '-Wl,--no-as-needed']

ccache can be used to cache and rebuild quicker as well:

1CC="$(which ccache) $(which gcc)" CXX="$(which ccache) $(which g++)" FCC="$(which ccache) $(which gfortran)" meson setup b2dir --native-file nativeFiles/mold.ini

Or in another native file:

1[binaries]
2c = ['ccache', 'gcc']
3cpp = ['ccache', 'g++']
4fortran = ['ccache', 'gfortran']

This can be called in a cascade:

1meson setup b2dir --native-file nativeFiles/mold.ini --native-file nativeFiles/ccache_gnu.ini

Further improvements come from ccache with distcc, or icecream or for a single binary extension, sccache.
