As CGF said, it would be reasonable to bet that it's now slightly
slower, not faster.  Nothing was changed in terms of the slowest parts
of Cygwin (ie, the fork emulation) except for allowing larger
environments, which, without looking at the code, just seems like it
would necessitate more copying and thus slower fork times.  But, all
of that is just conjecture.  Why don't you run some benchmarks for
yourself to find out the performance differences now, while any
problems you find might still be able to be optimized before the final
