Hi guys. Need your help. Last time has seen the strange peaks in the graph of CPU load. They appear randomly and do not depend on the number of users and traffic. Tried different versions of RouterOS - the same result. Hardware is good. You can see in the screenshots, as it happens. What could it be? Logically, it is pppoe and nat loads mikrotik, depending on the number of users and traffic. But it happens randomly...
Intel ® Xeon ® E5504, 4Gb RAM, Gigabit lan adapters
external uplink - load up to 140mbit
users - up to 200
type of authorization - pppoe
