Hello experts,

 

Recently, I deployed two units of TP-Link VPN router. TP-Link ER8411 and TP-Link ER 707-MY for site-to-site VPN. Since deployment two days ago, I noticed that the CPU utilization on TP-Link ER707-M2 is almost 15% during idle time. It is understandable that this may be due to VPN processing, but shouldn't CPU utilization be below (at least) 10% during idle time, even when the VPN feature is on? By the way, I'm using just a few configurations (IP routing and VPN) for this deployment. I do not enable any feature such as deep packet inspection. From my experience with other router solutions, most are at 5-10% utilisation during idle time.

Thanks.

Hi @bambinotenchie 

Thanks for posting in our business forum.

CPU could remain at a high level but it does not mean it is a problem.

It remains at a high level constantly because possibly the current enabled features require that level of CPU. So, that it keeps at that level.
