Subject: Re: skip-chars-forward v. re-search-forward

Message-ID: <E19126X-0005aH-00@fencepost.gnu.org> (raw)

    I've tended to use skip-chars-forward instead of re-search-forward
    since it's byte-coded and I assumed it's more efficient.  However, I
    made a measurement and found that skip-chars-forward was actually
    slower than re-search-forward.

That is really surprising.  Can you figure out what makes
skip-chars-forward so slow?  We ought to be able to make it faster
than re-search-forward without much effort, so we may as well try.
