[cellml-discussion] Cellml website access speed and IE7 warning

[Wilfred Li]

1) The data reported is from a CLI in cygwin terminal, so least amount
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.

4) See 1).

	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
