Liveview connection hanging with slow internet access

with liveView 0.5, but also the latest 0.12, I experience very long establishment of the connection (the page is then unresponsive), and then after I get the cursor, the live View update is reasonnably fast.

what could cause that ?

all the site responds normally, with that rather slow connection, but the liveVIew often hangs for a very long time and finally succeeds.

thanks for any advice

Did you find anything?

no and I did not experience it with latest relases

Yeah, I fixed my issues by reducing the size of the session to be sent across.
