okay,

i have this image from ethereal.

the blue line is the throughput of a http page with only text without
any encryption
the red line is the throughput with encryption.

does that look correct?
theres only simple text on the page, no images or javascript.
This looks fine, as when you use HTTPS, the browser first needs to establish a SSL or TLS connection with the server. This connection setup takes some more time (and bandwidth) due to the SSL/TLS handshake and the encryption once a code and cipher have been agreed upon. Once this secure connection has been established, an HTTP request-response is being transmitted over it. this explains the noticed delay between the blue and the red line. 

Best regards,
Olivier
