Well one second is quite a difference. I'd say you're on the right track!
The fact that "DocumentComplete didn't fire" is your clue. It didn't
download the complete web page!
Again, the only legitimate test is to save only a text file in order to
compare the two. I'm sure you can find a web page that consists of nothing but
text in order to test it if you really look.
If you want a tool to save web pages to disk, you should learn the various
File Save As options in IE a little better. There's a "Save Complete Web page"
option that saves all page related components in a sub folder. It still may
have a problem resolving java applets or ads being called from Ad servers in
most commercial web pages however. As I said, you need to make sure the HTML
source code isn't referencing any urls! It has to be static HTML (like pure
ASCII text).
Obviously wouldn't even want to save ad pages, so for a generic saving of
any web page, now you're dealing with on-the-fly editing that stuff out of the
HTML code you save to disk. Tsk, Tsk, Tsk. The life of a codehead...

And now I am totally lost !
I have tried and removed my Virus checker, but it made no difference. Same
result 5sec from the net, 10sec from MHT, 25sec fgrom HTM.
Then I unplugged (literally) my Internet (cable) connection which resulted in
the following:
The browser did not load from the MHT file at all.
The HTM file was loaded within a second, which is what I would expect rendering
from a disk file, although the DocumentComplete did not fire.
The whole object of this excersize is to load web pages from disk. It seems
that the method of saving and loading web pages from disk is at best a pretty
crummy implementation.
By now I have tried all different method of saving web pages, directly from the
net WITHOUT a web browser (as an MHT), which works OK but does not download the
complete page (it seems the style sheets are missing).
I tried using IE explorer(V8) to save the page as an MHT file which works
perfectly, but the load time from disk is prohibitively slow.
Have I missed something, or would I have to pursuing this project?

When you loaded from the saved files, it still probably had to resolve
the server to load extraneous graphics and java applets, etc. When you test,
you should make sure you're loading a static HTML file that doesn't have to
resolve anything to the server. There shouldn't be any paths in the file
pointing to the internet. It would be best to have access to a server so you
can load a text file and load that from disk and the Internet. Otherwise you're
comparing apples to oranges.

Hmmm... you must have worked for Microsoft tech support at one point, Dave.
Bob,
Try loading an HTML file, instead of an MHT file.

Have you run the tests with your anti-virus software disabled
"temporarily" ? (some are better than others and not everyone has the same.
food for thought.)
