Yes, I'm well aware of that - but your average viewer isn't going to notice expanded resources, however they ARE going to notice things like time-to-first-byte and network transfer.
EDIT: Just to be clear since I can't edit the older comment - instead of bundle size it would have been better to say that the "network transfer size" is roughly comparable.
Bytes transferred over the wire don't equal actual file size (due to gzipping, etc). Your page actually weighs 21MB.
