SPDY increasing size of pages

[steve willing]

Hello,

After enabling SPDY, I noticed that every element that loads on my site is larger (in bytes) than without SPDY.

This includes all elements, images, css, js and html.

Some log snippets below.

Notice how even when cached (304 not modified) it shows the bytes being even *larger* than the non-cached version.I should also note that I have tested this in the latest version of Chrome and Firefox, both have the same results.
