But as I noted in my original post: It's not waiting on the disk reads. Comment out the split() call and watch the delays disappear. Raw I/O speed in cygwin is comparable to mingw or MSVC. The overhead is due, somehow, to activity within/under split(). Other than allocation, that function doesn't do any meaningful library interaction that I can see (although Vaclav's suggestion about exception handling is a very good one...).
Can you port the testcase you provided to C to see if it makes a difference, please?
Or maybe at least try -fno-exceptions...
