Safari has become very slow to load pages. 5 to 10 seconds to begin to display a page. The problem is isolated to Safari on this computer. Other systems and browser are ok.
The system is a 13" Early 2011 MacBook Pro running El Capitan 10.11.6. I have done all of the stuff I would normally do to diagnose as problem: run Disk Utilities, purge caches, check permissions, login via a clean user account, etc.
In Console.app I notice that the system.log is getting filled constant stream of with messages from launchd related to Safari. Most of these are related to WebContent
and WebFeedParser
and History
.

To a lesser extent there are also ones related to ImageDecoder
:

Any ideas of why these are getting through into the system.log
, if they are related to Safari's slowness, and how to fix.
softwareupdate -ai
reboot and repeat 2) making a new user account, logging out of the current user and opening the same web page
