If I build the docs I use 'extractpdfmark' as well. In the light of
this thread I tried ghostscript self-compiled from their most recent
master, giving me 9.57.0.
Though, compile time is bad:
Always doing
time make LANGS='en' doc -j5 CPU_COUNT=5
I get for

Uncompiled guile

real    111m56,272s
user    190m51,445s
sys    17m51,542s

Compiled guile

real    98m43,545s
user    162m33,293s
sys    15m33,015s

This is insane. Tbh, I did not check whether pdf links are present but
directly downgraded to gs 9.55.0, with below timing values:

Uncompiled guile

real    50m20,112s
user    129m33,921s
sys    17m42,618s

Compiled guile

real    44m32,826s
user    116m10,453s
sys    17m1,201s


Better, but still bad, regarding the fact I compiled only the english docs.

Yes, I have a weak laptop...

No idea, if we can do anything to improve the situation.
Anyway, I thought I share my observations.

Cheers,
