Why did Mavericks slow down my MBP?

Did some digging in Discussions and found that a slow-down problem is common after installing Mavericks.

EtreCheck was recommended as a diagnostic first step. I have a report but I am not confident to act on any items without advice. Here it is - help appreciated.
