hawt.io poor performance

Hawt.io performance is poor. Even with refresh interval set to only 10s.

Broker installations with around 200 queues, 100 consumers and 100 producers.
This means that we need to set the Jolokia "max collection size" to unlimited (0) in our preferences in order to see all data.
With this setup:

• just scrolling up and down the list of queues in the left panel shows a typical lag of several seconds.
• expanding an item listed or selecting a menu shows a typical lag of several seconds.

This actually makes the whole browser very slow, not just the hawt.io window.
