For the last month at least the site's responsiveness has been atrocious. Today, on average, from the time I click on a link until the time the page finally responds is 25 seconds or more. Once it does finally respond the page loads rapidly so the issue is on the DB end, not choked bandwidth. It makes trying to shop an exercise in frustration.

EDIT: just posting this comment took 47 seconds from the time I submitted it until the page finally accepted it and updated.
