Besides the fact that it is better to use a linux box, look here http://docs.geoserver.org/stable/en/user/tutorials/feature-pregeneralized/feature-pregeneralized_tutorial.html
Another tutorial with postgis from a user is here http://osgeo-org.1803224.n2.nabble.com/attachment/6137141/0/pregen_tutorial.html The basic idea is to precompute generalizations of your vector data. This technique reduces the number of vertices which have to be processed by geoserver for each request.
