The document compares the performance of running Groovy scripts directly versus using the GroovyServ server. It runs a simple "Hello World" script three ways: directly with Groovy, with GroovyClient, and with GroovyServer. GroovyServer has the best performance at 0.029 seconds while direct Groovy is the slowest at 1.806 seconds. It also shows how to start the GroovyServer and an example of finding even numbers in a list that results in an assertion failure.

def list = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
