SPJeff (Jeff Jones) has just uploaded and shared his personal Best SP Warm Up Script to Codeplex: https://spbestwarmup.codeplex.com/
He combined multiple different solutions into his version.
Please feel free to check it out and use it as judiciously as possible!
Here are a few Key Features:
· Supports both SharePoint 2010 and 2013
· Supports custom page URLs
· Automatically detects all Web Application URLs
· Downloads full page resources (CSS, JS, images) not just HTML
· Downloads using Internet Explorer COM automation
· Great for ECM websites to help populate blob cache
· Warms up Central Admin too. Faster admin UI experience!
