Hello jojelino, I just rebuild cygwin1.dll latest snapshot. > I believe the attached patch workarounds delayed wait_sig problem. Yes - it works fine! > This yielded speed improvement. i ran your testcase and same timestamp > recorded 35. approx 2x speed. XP/32 Win7/64 cygwin snapshot 2011-07-21 34 12 cygwin snapshot 2011-07-21 SIGPATCH 44 37 As you see XP and Win7 now a really faster. Win7 3x speed - wow. > but i can't make sure it doesn't include side-effects. please test it on > your pc. let's hope it would work. I will test ist. I've already recognize one positive side effect: The CTRL-C Handler works now even faster. With unpatched cygwin1.dll there was a realy long delay, after pressing CTRL-C. Can you agree this too? I'm very interested if this patch will be released or not. I'm interested in the opionion opinion of C. Vinschen and C Faylor. best regards heiko -- 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
