Management Interface has become slow and unresponsive.

As we deploy more and more applications behind our F5 load balancers, the web gui has become slow and unresponsive, sometimes to the point where the gui loses connection to the LTM's. The deployment currently consists of a pair of 3600's in HA running 11.3.0(Build 3131.0), with the following elements deployed:

 

  • 201 virtual servers
  • 125 nodes
  • 242 pools
  • 210 monitors(some might not be active)
  • 148 http class profiles

As it stands traffic is not currently being impacted by the issue, however as more objects get moved to the device management becomes more impacted. We are currently peaking at around 10000 active connections, however load does not appear to be the cause as we currently only have ~3000 active connections and the responsiveness is the same.

 

I know there could be numerous reasons why the management interface is slow, but in the communities experience what is likely to be the cause.
