I wrote lot of FORTRAN programs using massive formatted file outputs. When passed from 1.3.22 (one of last 1.3.xx) to 1.5.xx (all tested), the writing/reading performance of relevant SW modules slowed down to few % of before experienced performance (typically 20-30 times worse). When compiling the same code with -mno-cygwin, the performance increases again. Then, there are some cygwin1.dll entry points for IO functions that have been either strongly damaged or unoptimised ??
