Cygwin is a POSIX emulation layer. Using the POSIX emulation is bound to be less efficient than running the native application (which is what the MinGW gcc is). If you want to know wher ethe time's going, look at the strace output (don't send it to the list, though, as your times look quite normal -- I get about 1.6s on my system once gcc is in the disk cache). Also, in the future, please *attach* your cygcheck output to your messages as an uncompressed text attachment, instead of including it inline, since that produces false positives in archive searches.
