I tried running mirror later today:

Nov 02 12:42:47 mirror [info] Mirroring finished. 423 page(s) saved, 2354 
second(s) spent

I also am running it now, getting the same ~5 sec per page response time and 
uptime command states:

  7:49PM  up 10 days,  4:36, 4 users, load averages: 4.00, 3.22, 3.04

The database itself does not look slow, nothing like these 5 seconds to connect 
/ send the standard query.

Yes, that's one way to ask these questions. The other way is: why are we having 
response times of ~5 seconds for not-too-complex pages?

The only thing I'm doing differently from the current one is that I'm sending 
HTTP requests to get the pages. I already outlined benefits of this approach 
either here or in a private mail.
