<div>I really appreciate what Regex Coach has done for honing my Regular Expressions skills, and assisting debugging of complex expressions.</div>
<div> </div>
<div>I frequently wish to optimize regular expressions (mainly by reducing possible backtracking <a onclick="return top.js.OpenExtLink(window,event,this)" href="http://www.regular-expressions.info/atomic.html" target="_blank">
http://www.regular-expressions.info/atomic.html</a>), but lack a way to test the relative performance between different regular expressions.</div>
<div> </div>
<div>To measure performance of a given regexp, I would really like the possibility of having Regex Coach count the total number of steps used by the underlying regexp engine for a given regexp search, or some other meaningful performance indicator.
</div>
<div>This could possibly be displayed when pressing the ">>" (show next match) button (regardless of whether a match was found or not). This way, you can quickly try out different matching approaches, and get an indication of the relative performance.
