I did not see any version numbers or if we are discussing BSD grep or GNU grep. The grep in OSX is ridiculously slow. Whenever anyone says grep is slow the first thing I ask is if they are using OSX, the answer is almost always yes. GNU grep is a lot faster. That being said there was a bug with grep and UTF a little while back. Debian lists the bug as present in 2.6 and fixed in 2.8: "grep ." pathologically slow in UTF-8 locales -- http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=604408 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=604408
