If you do your interfaces in Adobe Photoshop, then slice and optimize in 
Adobe Image Ready,
Image Ready will provide size and download times for each image slice as well 
as the
total.  I'm not sure if the download times take into account it's own 
generated code/layout
or just the images.  It has the added advantage of showing you optimized vs. 
non-optimized
images and even lets you visually compare up to 4 levels of optimization 
simultaneously.

downside, of course, is cost.
