Strange Network Behavior on Chrome:Cable for SSL Handshakes

[pganti]

If we were to plot the throughput at the server side and then the same at client side you can see the attached graphs which show that server sends like 14KB in one go and then like 30KB in second go. The client however starts really small hovers around 1.*K for a while before going to 3K then 4K and ending the transfer at 5K.

Given that Chrome Cable is 5Mbps atleast 600K is permissible and particularly when the server sends out at that rate, whats stopping the client here?
