Traffic Graph becomes unresponsive after a while

[nightflier]

After a few weeks with OPNsense, I am quite happy with it so far. 

I have three internal network segments, and find it very useful to keep the traffic graph running and visible. However, the page seems to put a heavy load on the computer displaying it. After a few hours the page freezes and shows a message about an unresponsive script.

I have tried different computers/Linux distros/browsers, all with the same result.

If this could be addressed, in current or future versions, it would be great.
