Im getting the exact same result on the same router

However mine doesnt build up but rather goes straight to ~25% and stays there, with the odd drop during the middle of the night (marked in yellow)

I previously had a dreytek and it was dual core, it ran pretty constant at 50% load for years without issue.   I dont think its anything to be concerned about

@Philbert I don't see a reason for concern either as there is no performance reduktion with my network, I just find it strange, and there my be a reason to this behaviour.

Hi,  

I have a similar problem with my TL-R605 connected to a TL-SG2008P switch and a OC-200 controller. 

I have to reboot my TL-R605 router every 30 -36 days. I think the memory runs slowly full till 60% (see both flat lines) at 60 % my TL-R605 router does not send any data to the OC200 controller anymore. Everything is working (still got internet etc) but i dont see any statistics on the OC200 controller and i cant change any settings on the TLR605 router. Local management isnt possible because its still controlled by the OC200. After a reboot the router send data statistics again to the OC200 controller 

TL-R605 version: 1.0.0 Build 20200930 Rel.36519

OC-200 controller version: 4.2.8

@Cyclups I am having the same issue. It starts to show a high CPU load and gets slower and slower so I need to manually reboot the router every few days. Has anybody proposed a solution? Is it possible to schedule an automatic reboot, say at 3 AM every day?

Disabling "IP Statistics" seems to have fixed this high CPU usage for me.

Status -> Traffic Statistics -> IP Statistics

@CRaj You are correct. Disabling "IP StastistIcs" fixed ever increasing CPU usage. Thanks!

@Cyclups Did you ever find a solution? I can't find the IP Statistics others mention in the Omada controller. At this point I'm considering a smart switch that power cycles the router at 4am.

Hi, firmware updates solved my problem
