For instance, scanning local directories is about 60% faster in 1.7 while starting lots of processes is about 10% slower on Vista but about 5% faster on XP, according to my testing. Further optimization will be a task for post-1.7.1, while for 1.7.1 itself we're looking primarily for functionality. Having said that, if you find source code in Cygwin which could be improved, feel free to point it out.
