SPDY increasing size of pages

Mon Aug 6 17:55:15 UTC 2012

Hi Steve,

I just did some tests: the logs reported 33KB on a .html file that's 805 
bytes. After refreshing it said 2.4KB, and after another refresh it 
claimed 1.1KB. For the record: gzip was disabled and with spdy disabled 
it reported 805 bytes like it should.

Then I looked at the response headers on the requests, which always 
mentioned 805 bytes on all responses, even with SPDY enabled.

Conclusion: there's no massive network overhead, the counter is simply 
broken.

Tom

> 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.
