Hi DPDK team,
I have big problem with temperature of CPU when running DPDK App (My app use all of 16 CPU on socket 1, and all CPU always run with 100% work load). As you see in below statistics, temperature of CPU is up to 72°C.
My question: 72°C is too hot, right?. What is the recommend for temperature of CPU when running DPDK App?
