Hi all,

I am not noticing any significant delay using JAWS with many links. For 
example, the 547 links in WCAG 2.0 load almost immediately; in the HTML5 
draft, with 773 links, it takes maybe half a second. With a test page 
created with 3.000 links (althouth they are exactly the same...), it 
took about 1 second to show the list. I think this is quite acceptable 
and not a real problem.

As far as I know, JAWS, NVDA and others create a copy of the DOM in 
their "virtual buffer" and then read from it, so there should not be 
significant delays. If the DOM is updated using proper techniques, the 
virtual buffer will also be updated, so the screen reader is always 
synched with the page contents.

In any case, even if a short delay exists, this should not be a reason 
to avoid the use of links, since they are being used to facilitate 
access, not to bother users. Nevertheless, it could be useful to provide 
complementary "no-links" versions of these type of documents that allow 
better reading experience for blind users.
