Group articles and bundle those together as mini-blobs before creating the 
large downloadable blob. Recalculate only the mini blobs that have changes, 
once every e.g. 10 minutes.  Recalc the bigger one every hour.  Not sure 
how naturally grouped the data is, but even an artificial grouping of e.g. 
500 articles per blob grouped by id should work.  If there's a way to put 
oft-changed articles together you'll save more.
