Go to dev, test, & management meetings – and ask those questions. Advocate performance through questions. Earning the “annoying” label for asking questions is ok, but becoming “annoying” via your response to their answers isn’t. Thoughts on Questions

12 www.PerfTestPlus.com © 2006-9 PerfTestPlus, Inc. All rights reserved. Performance Testing Software Systems Page 12 Why am I annoyed? How annoyed am I? Does this annoy me all the time, or just sometimes? Advocate something better. Thoughts on Annoyance

The end-user’s browser cache can be your best friend, or your worst nightmare, use it wisely. Get the load order of your scripts and styles wrong, and you’ll lose your users every time – even though response time hasn’t changed! 3, 4, & 5xx series response codes on individual objects are bad things. When it comes to performance, less is more (usually). What is SCORN, anyway?
