That's rather counter-intuitive. Just ran them myself and for me, match beats subst:

                   Rate length_subst         subst         match trans
+literation
length_subst     2080/s           --          -88%          -90%      
+      -97%
subst           17998/s         765%            --          -16%      
+      -77%
match           21423/s         930%           19%            --      
+      -72%
transliteration 76797/s        3592%          327%          258%      
+        --
