Hello, I have Mikrotik RB3011UiAS ROs 7.6.
Configuration:
WAN sfp 500 mb/s.
1 GRE tunnel without encryption
150-200 Mb/s traffic from GRE to LAN
30 Route rules, Standart Firewall(Fasttrack is enabled), 4 mangle rules(change TCP MSS), OSPF.
The problem is 95-100% CPU on one Core. Is it possible to optimize the configuration to reduce the load on the processor?
