Description (partial)

After upgrading, you may experience heavy lags caused by increased disk load.

If the WSA was running with increased update interval time, to reduce lags, that config change was lost on upgrade.  We now have 2 update settings, under updateconfig.  If you were running with 6 hour update intervals, after upgrade you will have:

Update interval for Web Reputation and Categorization: 5m
Update interval for all other services: 6h

That is completely backwards, the "Web Reputation and Categorization" updates are the ones that cause excessive disk usage, and you would want to reconfigure Web Reputation for 6 hours.   You want "interval for all other services" set to 5m, to get your AV updates in a timely fashion.
