As per my experience, GUI for 9.x is slow only. We recently switched to 10.x and the GUI is really fast. Web GUI enhanced in 10.x which is using AJAX and refreshes only related components than loading the whole page. The GUI was extremely slow over the WAN. We used to RDP to the LAN server and then launch from there.

The solution that fixed our configuration console using Firefox and Google Chrome was 
&nbsp; SOL10770: The BIG-IP Configuration utility may render slowly when using recent versions of the Firefox browser  
&nbsp; https://support.f5.com/kb/en-us/solutions/public/10000/700/sol10770.html 
&nbsp;  
&nbsp;  
&nbsp; When using some versions of the Firefox browser, such as 3.5.5, the BIG-IP Configuration utility may render slowly. Analysis of the traffic reveals that the sixth parallel connection that the browser opens has a 17-second delay between the time in which the TCP connection has established, and when the SSL handshake begins. During this delay, the page element that Firefox intended to request with the connection is held up. When this issue occurs, a user will see the Configuration utility begin rendering and then stall for approximately 17 seconds. Eventually, the SSL handshake will complete and Firefox will download the remaining page element. As a result, the Configuration utility will finish rendering.

&nbsp;  
&nbsp; Solution is increases the "MaxClients" from the default of 5 to 20:  
&nbsp; bigpipe httpd include '"MaxClients 20"'  
&nbsp; bigpipe save all  
&nbsp; bigstart restart httpd
