A bit sluggish here with Firefox 1.0.5 (from ports). Page loads in
approx 30 seconds. Once the page is loaded, other pages are served
almost instantly. Stopping firefox and restarting it, results in the
same initial delay.

With w3m, every page access results in that approx 30 secs delay;
perhaps because w3m doesn't keep the connection open?

It could be DNS related. I've run
$ truss w3m http://www.anz.com.au/

after mounting /proc, and most of the waiting time is spent querying
the local DNS server. After getting a reply from the DNS server,
everything starts running smoothing and fast again:
