Ouch, I wasn't intending to make work for you!  Even if the patch in 
<http://bugs.gnu.org/16481#14> didn't improve performance, it makes grep 
simpler and that should be a win.  Norihiro Tanaka's patch (which I'd 
forgotten about, but which is presumably better) also simplifies grep, 
so you shouldn't need to do a performance analysis to verify that it's a 
good idea.
