Doctype

Does specifying the DOCTYPE tag slow down the loading of your page in
general?

With:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

will the browser visit that URL first?

No. At least in this case, browsers have that info ready to go.

It adds a few bytes to the filesize, but otherwise no.
With:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">

No.

In *general* it might, but since most browsers do not really
parse according to the stated DTD - and parsers or browsers
that do parse will almost certainly have local copies of common
DTDs such as the one below, you won't be delayed unless you
are using an odd DTD. If the name of the DTD isn't recognized,
then a proper parser should look up the url -- in other words,
you should be able to write your own DTD and put it on the
web with an appropriate name. Don't hold your breath until
common browsers pay attention to your personal DTD.

If you want to omit the url for common DTDs, you can do it.
It just won't make any difference.
With: <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd"> will the browser visit that URL first?

Omitting the URL will throw many browsers into quirks mode.

In most cases only on a Transitional doctype, not Strict.

Mac IE 5, HTML 4.01 Strict without URL => quirks

Fair enough. That's why I said *most* - I figured there'd be at least
one where that wasn't the case. :-)

Certainly at least for Mozilla and IE6 a Strict doctype triggers
"Standards" mode, regardless of whether the URI is included. I'm sure
there are several others, too (including Opera I think).

Anyway, best to include the URI, if even one browser goes into Quirks
mode without it.

I wouldn't exactly grant a dead browser that admittedly will be kept
alive for a while on legacy installations of a dead minority OS the
status of covering 'most cases'.

Mac IE 5 has been pretty much supplanted by Safari and Firefox, but the
Mac OS, though certainly minority, is hardly dead.

You *want* to misunderstand that, don't you?-)
The Mac 'classic OS' (hence 'legacy installations') *is* completely
utterly dead. That's where IE Mac usually is the 'browser of choice'
(not to say the browser of no choice).
I actually do know a lot of people in real life who use OS X, and I've
never seen anyone using IE Mac (why in &deity;'s name would anybody even
want to?).

Hey, there's always iCab!

Very good question.
