This may well be slower than just loading the document and being done 
with it.  In fact, the slow part of the html5 spec single-page load is 
precisely the operation you describe: dom fragments being loaded via 
ajax and sprinkled about.  It's slow in all browsers (e.g. in Safari 
this operation takes about 2x as long as the pageload itself).

Until you try to do a "find in page"; something that needs to be done 
with depressing regularity for specs.
