Slow browsing after upgrade to Mavericks and SAV for Mac version 9

In simply terms: Web Protection works by taking the URL requested in a browser, pausing the connection, then checking in with a list SophosLabs maintains (globally available servers that are very fast) to see if it's malicious or not.  If it is bad then it's blocked and the page you see is a blocked page, otherwise the request is given back to the browser to carry on its connection.  Obviously doing that is 'extra work' and there may be a slight delay.  It's when the delay is quite noticable that we can look into it.  The technology has to check with central servers as the list is always being updated and you wouldn't want it locally on your computer.

I've spoken to our development team and they will comment.  They may ask you to look at the page load speed via Safari's or Chrome's developers options so maybe you can start to look at that and see if you can spot something loading particularly slowly in one of the example site.   Example of Safari:
