But it begs the question of how many other basic and take-for-granted functions might be affected by this apparent UTF-8 slowdown. And again we, are not talking about some minor overhead, we are talking about a slowdown of 1500X or 150,000%!!!! As a North American English speaker, UTF-8 is not that important to me and certainly not worth such a heavy overhead price. Also, while I don't have 'pcgrep' installed on my machine, it is interesting that 'sed' is not affected. -- View this message in context: http://old.nabble.com/1.7--BUG---GREP-slows-to-a-crawl-with-large-number-of-matches-on-a-single-file-tp26224019p26249599.html Sent from the Cygwin list mailing list archive at Nabble.com. -- Problem reports: http://cygwin.com/problems.html FAQ: http://cygwin.com/faq/ Documentation: http://cygwin.com/docs.html Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple
