It should be noted that the benchmark Terry is describing fires up
N concurrent backends and then measures the runtime for a specific query
workload.  So it's not measuring connection startup time, which is
alleged by some to be Cygwin's weak spot.  Nonetheless, I invite the
Postgres-on-Cygwin-isn't-worth-our-time camp to produce some benchmarks
supporting their position.  I'm getting tired of reading unsubstantiated
assertions.
