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

I've spent a little time seeing what impact Web Protection has on my browsing.  I have a relatively slow connection, and while I don't have access to a Mac right now, the Sophos Windows endpoint sofware does pretty much exactly the same thing on both platforms (though in my experience the Mac version is a little faster).  I'm using the Chrome browser.

For me, browsing to amazon.com takes 5 seconds before any content appears, and another seven before the spinner stops.  Turning off all web protection sees that drop to two seconds and five.  Content scanning only is 3 seconds and five.

The content scanning result (no reputation checks) is as expected.  It is stopping the browser seeing any content until each element has been fully downloaded -  for the main HTML page that's about a second delay.

Since the reputation lookup result may reasonably be expected to be available before the content scan occurs, it is clear that for me at least there's some delay to the real-time lookup.  The lost two or three seconds on a site like amazon isn't too bad considering the hundreds of lookups and scans which are needed to keep me safe.  Having said that I think it could be improved, and so warrants some further investigation (and this time with a Mac!).
