--- Comment #2 from Martin Liška <marxin at gcc dot gnu.org> ---
Yes, I can confirm also other testers reports slower compilation of WRF:
https://lnt.opensuse.org/db_default/v4/SPEC/graph?plot.0=2.270.8

I know the benchmark contains a huge config module that delays the compilation
rapidly. Moreover, one ltrans always runs much longer than the others.
