The first execution of an IWS Service which executes a Groovy script after a system reboot incurs a couple of performance penalties both related to groovy.

1. Because any service script can possibly contain a groovy step, groovy class loaders are initialized taking more than 10 seconds in some scenarios
2. If a script actually contains groovy members the initial groovy compile requires even more compiler configuration

These delays cause upstream transactions to timeout, and locks can be seen in java stack traces in the groovy compilation tasks.
