Hello Alexandros, Thanks for your reply. The version of my kernel is as follows:
Linux e9f62e632fd0 3.13.0-77-generic #121-Ubuntu SMP Wed Jan 20 10:50:42 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux The information about CPUs is: Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 12 On-line CPU(s) list: 0-11 Thread(s) per core: 2 Core(s) per socket: 6 Socket(s): 1 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 63 Stepping: 2 CPU MHz: 2397.332 BogoMIPS: 4794.66 Virtualization: VT-x L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 15360K NUMA node0 CPU(s): 0-11 I reduced number of clients to 1 but the problem persists. Is there any other cconfiguration for specifying the number of working threads of httperf (by some other config file)?
