Problem

• Users might observe that the JOC Cockpit GUI becomes slower after some hours of work. The precise period when this happens is not precisely predictable.
• Slowness includes that for example typing of characters is delayed in the GUI.
• This problem occurs more frequently with FireFox than with browser products such as Chrome, Safari etc.

Analysis

• Garbage collection of unused web data is not perfect with browsers.
• In fact - depending on the operations of a user in the GUI - the browser might not cleanup unused web data which slows down the JOC Cockpit GUI.

Solution

• Refresh the browser page. This forces unused web data to be removed.
• It is not required to clean the browser cache.
