of overhead presumably.

I must say that I'm on a 11 Mbps line at a hotel in DC, yes, they still
have these evil 11 Mbps lines in our capital. Just for comparison:

The DNS resolution appears to be sluggish, besides the transfer rate.
2,3) Apparently IE is slower than the other browsers because it has to
process this warning about MSXML 5.0 on every page. Opera 9 loads the
first page very slow, maybe 10 sec, but then the other pages are quite
fast. My firefox is set up with UCSD proxy, so it'll be slower, and I
don't use it normally.

Hi, everyone,
It seems that the access speed from North America to
the website is
rather slow,
Network latencies and throughputs from New Zealand -
US are always going to be slower than the typical
speeds within each respective country, so I'm not sure
if this is normal or not. It takes just over a second
to load and render http://www.sdsc.edu/ from within
Auckland, as opposed to under a second for
http://www.cellml.org/ (obviously, the pages don't have
exactly the same amount of data required, and this is
in Firefox, so this might be different than for you).
I'm also not sure if you mean the network speed or the
page rendering speed, so a few things to try that might
narrow it down:
1) Can you give us some quantitative measure of what
you mean by slow. I would recommend something like the
following:
time wget -O - http://www.cellml.org/ /dev/null
If this is fast, perhaps the time it takes for a
complete page reload in your browser might be useful
(Shift + F5 in most browsers).
2) Does the slowness happen for all pages or just some?
3) Is there any difference between browsers (e.g. is it
just as slow in Firefox)?
4) How long does it take for http://www.auckland.ac.nz
to load in your browser?
and I keep getting the warning from IE7 about This
website wants to
run the following add-on MSXML 5.0, ...?
Does this happen when you try to open a CellML model in
IE or even on normal pages? Can you narrow down when
this happens?
Thanks for reporting this issue,
Best regards,
Andrew
