Does anyone know about minimum requirements for the data rate depending on using Plugin or Ajax? Are there different conditions?
We´ve got the impression that IE Plugin needs higher data rate for working fast, but does anyone has facts or an assertion to prove it?
Hello Pascal,
My guess is that your client or server is not able to reach default Plugin - Server communication port 4747 (either in outbound or inbound connections, probably because of some sort of firewalling/NAT), and then falls back to tunnel (port 80 standard http), which increases the network traffic. If the server uses https, the response times may be slower and higher data traffic would happen.
Check the Server Reference manual par. 17.2 (version 9).
Hope this helps.

Hi Miguel,
thanks for the informations.

Can you explain it technically why the network traffic increases with using a different port?
Although a sniffer would do a better job, the communication communication using 4747 is done directly between the client (IE Plugin) and the server (QVS), so all security information is passed from client to server. When tunnelling, a web server appears between client and server (usually the QlikView WebServer or a IIS) so all those security packets and the information itself must be formatted to whatever language is required between Server to WebServer and then WebServer to client (Browser).
It's not a question about ports (you may change or route the port) rather than a protocol issue. QVP (used by IE Plugin) talks directly to QVS, while QVPX (Ajax) talks to a WebServer and then this talks to QVS.
Hope this makes sense.
Thank you. That helped a lot.
