BIG-IQ GUI slowness issues

When I accessed a BIG-IQ today I noticed that it seemed to take a long time to load. Some checking revealed that it the total weight approached 15MB before it was done loading the really heavy stuff.

The main culprit seems to be /mgmt/shared/index/es-config, which is loaded numerous times. Sizes are as follows in my case:

• 66.5 kB
• 1.9 MB
• 1.9 MB
• 637 kB
• 1.8 MB
• 3.2 MB

This is followed by hundreds of small downloads of that resource (around 1.5-2.0 kB).

Anyone else who has encountered this behavior? I dread being stuck with a slow hotel WiFi-connection if I have to access BIG-IQ...
