Please help with a problem I have had since upgrading to latest Cygwin DLL. When I do IO using fopen it is many times slower now than IO using simple open. Also programs like sort and cut have very slow IO access times. This behavior is not seen when I compile my own programs with the -mno-cygwin option in GCC. A trace of the program execution shows that large delays seem to occur with system calls labeled "set_flags". I attach an example program with comments showing the relevant timings and trace excerpts. Also I attach output of cygcheck for my system, in compliance with request on website. Thanks for any help. -- Joseph Rosenzweig
