Wavelink Avalanche Poor UI Performance

Hi All,

                We are using Avalanche 5.3.1.50. We have 260 Mobile devices. 

We are experiencing really poor UI performance in the Avalanche Console and Web app.  It takes over a minute to populate the UI.  Does anyone have any performance tips?

We are displaying the following columns:

Serial | Terminal ID | IP | Last Contact | Recent Activity | Notes | Sync State | Device Name

The performance has degraded as we have added more devices.
