Hi MW,

 

 

I'd start troubleshooting this with a browser plugin or proxy on the client. You can use HttpFox for Firefox or Fiddler2 for any browser to trace the HTTP requests and responses. Once you have an idea of when the latency is occurring, you can try testing against a test VS with the same configuration. If you need to decrypt the SSL, you can use tcpdump to capture a trace and then use ssldump to decrypt it. There are solutions on AskF5 and a lot of online resources for using tcpdump and ssldump.
