A W3C note that discusses network performance effects of HTTP/1.1,
CSS1 and PNG is available [1]. The paper is a bit rough due to a
submission deadline, but shows important numbers. All three
technologies contribute toward increased network performance.

For the given test document (which is a concatenation of Microsoft's
and Netscape's home pages), HTML+CSS1 can replace 22 of 40 images and
reduce the size of others. In bytes, the total saving is 23K. Since no
browser can yet render the full HTML+CSS1 replacements, the numbers
are estimates that will need to be confirmed.
