+        * textmodes/tildify.el (tildify-ignored-environments-alist):
+        Optimise environments regexes
+
+        Each time beginning of an environment to ignore is found,
+        `tildify-find-env' needs to identify regexp for the ending
+        of the environment.  This is done by trying all the opening
+        regexes on matched text in a loop, so to speed that up, this
+        loop should have fewer things to match, which can be done by
+        using alternatives in the opening regexes.
+
+        Coincidentally, this should make matching of the opening
+        regexp faster as well thanks to the use of `regexp-opt' and
+        having common prefix pulled from many regexes.

         * textmodes/tildify.el (tildify-string-alist)
         (tildify-ignored-environments-alist): Add `nxml-mode' to the list
         of supported modes since `xml-mode' is no longer a thing but just
