Saving it too. Can you time both and show the exact timings? Also, the file should not be plain ASCII (and probably not UTF-8, either), so that decoding the text is included in the comparison. > (while (re-search-forward "taylan" nil t) (ignore)) in the same fil= e is > pretty much instant on both. Once again, please show exact timings. "Pretty much instant" could b= e 0.01 sec vs 0.02 sec, which is still twice slower. Thanks.
