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
