[SR-Users] rtpengine cpu usage

Hi guys, I'm using rtpengine (compiled from source) and I see a lot of difference in cpu usage comparing with rtpproxy. Is this normal? With 600 calls: cpu *41.7%* rtpengine #rtpengine threads 4 # lscpu Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian *CPU(s): 2* On-line CPU(s) list: 0,1 Thread(s) per core: 1 Core(s) per socket: 1 Socket(s): 2 NUMA node(s): 1 Vendor ID: GenuineIntel CPU family: 6 Model: 26 Model name: Intel(R) Xeon(R) CPU X7560 @ 2.27GHz Stepping: 4 CPU MHz: 2259.955 BogoMIPS: 4522.00 Hypervisor vendor: VMware Virtualization type: full L1d cache: 32K L1i cache: 32K L2 cache: 256K L3 cache: 24576K NUMA node0 CPU(s): 0,1 Calls established with a=rtpmap:0 PCMU/8000 Thanks in advance!
