Hi, Does anyone know if there is a DPDK provided tool to measure latency of a packet traversal (i.e., when a packet is copied from the NIC to userspace)? Also, we are using rdtsc to measure processing delay in the userspace currently, but does anyone else have suggestions/experiences for other tools? Additionally, we want to locate the latency bottleneck. Has anyone looked into this? Would you share your experiences please?
Thank you very much. Jun
