We have tested our SRX firewall with iperf the strage behaviour we observed. That is when we initiate a traffic with frame sizes 64 till 512. We recieved extensive CPU on UDP based traffic but with same frames sizes when we compared it with TCP we didn't find SRX extensive CPU.
We are just trying to understand what can be the possible reasons that UDP is more CPU extensive rather than TCP.
Logs are mentioned below for reference.
We have different things in mind,
1. Either its device scalability issue. We have SRX240 right now.
2. Do we need to introduce any kind of QoS/Rate-limit.
