It's almost certainly the console output.  That's always been my main
quibble with Cygwin: working with cygwin bash is almost unbearable to
me, because terminal output is so unbelievably slow.  It feels like my
old 25 Mhz '386 running raw DOS, when it didn't have the video BIOS
shadowed to RAM --- when it's actually a 1Ghz Athlon running Win98.
It's almost painful to watch some 20 screenfuls of 'ls' or 'cat'
listing scroll by.

Morale: if want speed out of Cygwin, be very sure to turn off all
console output.  Or at least redirect it to a file or /dev/null if you
want useful performance figures of the compiler itself.
