Basically it is,

  (search-forward "call_")

versus

  (re-search-forward "\\([^\n]*?\\)call_\\([^()[:space:]\n]+?\\)\\(\\[\\(.*?\\)\\]\\|\\(\\)\\)(\\(.*?\\))\\(\\[\\(.*?\\)\\]\\)?")

Of course, the speed factor depends on the length of the lines in the
document, but it could make a significant difference for the OP.
