I have noticed it as well. This page generated in less than 2 tenths of a second however (with 15 queries, forget to get server loads). In the past few weeks I've seen load times close to 30 seconds on occasion.
I'm on a DSL connection right now, but I believe the page "generated" statistics are not tied to your connection speed, but rather how fast the server produced the page.
Hopefully Clarity can look into this. I know the eStore is/was having some effect, plus some type of "remove white space" feature was suspect, and we suffered a DoS/bot attack of some sort as well. All problems that could be the culprit or compound some other unknown issue(s).
