Problem

• Users might observe that the JOC Cockpit GUI becomes slow after some hours of work. The precise period when this happens is not predictable.
• Slowness means that, for example, the 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 a user is carrying out in the GUI - the browser might not cleanup unused web data,  slowing down the JOC Cockpit GUI.

Solution

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