Are you running on a 64-bit Windows OS? Cygwin's process creation on 64-bit Windows is currently ~6 times slower than on 32-bit Windows. On 32-bit Windows, Cygwin's process creation performance is ~3 times slower than Microsoft's Interix (SFU/SUA). It might be best to treat this as a Cygwin issue rather than a GNU make issue. I've been meaning to look into why Cygwin is performing so poorly here, but
haven't been able to scrape together time to do so.
