hi,
The site is very slow in 90% of the cases for me for some reason, can you confirm ?
When I click between the links on the top right sometimes it is in the range of 15 sec, sometime in the range of 30 sec.

wget -v perlmonks.org
--12:22:39--  http://perlmonks.org/   => `index.html.2' ...
12:23:21 (97.07 KB/s) - `index.html.2' saved [65659]
[download]

The interesting thing is that when I debug it with firebug the total load time of the html and css :

http://perlmonks.org/css/common.css
http://perlmonks.org/?node_id=204962
[download]

it says something in the range of 100-200ms. It seems that it stales for ~20sec and then fetches everything for ~150ms.
The network seems to be ok (97K/s).

ping perlmonks.org -s 1400

I haven't done any tweaks on Firefox.
Do you experience slowdown or it is only me ?
