Hi,

 

I would check your DNS settings...

 

If you have "Display Host Names When Possible" enabled (under preferences on the gui) and the names of pool members/nodes are unresolvable the F5 GUI will sit and wait for a DNS timeout (a few minutes). This happens even if it's not actually displaying the names, but is displaying something that could be resolved in DNS.

 

 

I had a similar problem, and found that some sections of the GUI were faster than others (iRules for example). Eventually, I found that my DNS settings were wrong (pointing at valid DNS servers but on an unreachable LAN). Once I corrected this the GUI started responding quickly again.
