  • I'd like to suggest that you include a second test for Google BlogSearch to make the comparison to PubSub a bit more fair. What you're retrieving from PubSub is an Atom feed, not a full HTML page. Typically, HTML pages can be filled with all sorts of junk that isn't present in Atom feeds. Thus, the Google BlogSearch numbers may be getting dragged down by them having to transfer more data or do more formatting of the output. So, what I'd like to suggest is that you include a second "Atom" search test for Google BS that would look like this:



    http://blogsearch.google.com/blogsearch_feeds?s...>


    Since PubSub always returns 32 results (if present) it makes sense to adjust the Google BlogSearch item "num" to be 32. Admittedly, there would still be a difference between PubSub and Google BlogSearch since GoogleBS only returns summaries while PubSub returns full posts. However, this difference in payload size might get lost in the wash.

    However, PubSub will still come up on top; Google doesn't bother to compress their ATOM feeds.



    Ouch!
