My timings don't show great improvement, and a 1 second margin of error due to windows caching does not make it look that much better. Perhaps there is something else to account for the difference. The patch saved 6 +/- 1 second from the execution of the unopimized testcase. the most interesting numbers are Old DLL: 19.60 seconds snapshot DLL: 13.32 seconds Mingw: ~3 seconds. OT: I wonder what the performance is like with Interix (Windows Services for UNIX 3.5). Do they have a similar showdown problem? -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
