I am in trouble with my mikrotik router. When i have disconnected some user like 5-10, the router cpu usage getting high 80-90% thats why my running user suffering with packet loss and slow bandwidth performance for few seconds, Even for 1 user disconnection cpu usage getting 50-60%. In this situation my running users are complaining so much. I have tried latest OS as well as old version of OS, but nothing improved. In this case i need a solution badly. Please help me to out of this trouble.
