Hi All, I am using OVS_DPDK, and the target CPU has running 100%. However, I notice the cpu frequency is NOT exceeding the max value, so the performance may not reach the best value. I have 2 pmd only for now, each is hyper-thread core in one physical core.
I am not sure the reason, and do not get idea after going through the BIOS and googles. Can someone kindly indicate the root cause? I am using centos7. Appreciate your help. # cat /sys/devices/system/cpu/cpu4/cpufreq/cpuinfo_cur_freq 2599980 ---------àI expect it would be 3000000 # cat /sys/devices/system/cpu/cpu4/cpufreq/cpuinfo_max_freq 3000000 # lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 64 On-line CPU(s) list: 0-63 Thread(s) per core: 2 Core(s) per socket: 16 Socket(s): 2 NUMA node(s): 2 Vendor ID: GenuineIntel CPU family: 6 Model: 79 Model name: Intel(R) Xeon(R) CPU E5-2683 v4 @ 2.10GHz Stepping: 1 CPU MHz: 1199.953 BogoMIPS: 4195.88 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 40960K NUMA node0 CPU(s): 0-15,32-47 NUMA node1 CPU(s): 16-31,48-63 Br, Wang Zhike
