If you make your own command kpsevarinfo by replacing
cnf.c by cnf2.c, where in cnf2.c kpathsea_init_db (kpse);
in the line 250 is omitted,
kpsevarinfo -var-value=TEXMFHOME
may be about 10 times faster than
kpsewhich -var-value=TEXMFHOME

Note that kpsevarinfo may be usable only to obtain
information on variables.

Best,
Akira
