I asked on the call today about performance on hub, and I've done
some further testing.

What I'm seeing is a lag in accessing a page. Basically, for every page
I view there's a brief pause (maybe 1 or 2s, enough to be noticeable)
before the page starts to load.

I'm seeing this from home and work - both Ultra 20s with firefox 3.5.2.
Retrieving a page with wget shows exactly the same pattern - it connects,
then there's a definite pause before data starts coming back.

I don't see this on the current opensolaris.org site. So it's not network
latency. (I'm in the UK, so there's going to be *some* delay.)

I've tested this with wget repeatedly:

% ptime wget http://www.opensolaris.org/os/about/faq/getting_started_developers/

For the latter case, the download itself (given the size and the reported rate)
is about 2.4s, leaving about 2.5s unaccounted for - and it's obvious when I
run this that there's a long pause (about 2s, which seems about right)
after "HTTP request sent," before data starts coming back.

(It's also clear that the page weight has gone up, quite a lot in this case.)
