This presentation will show how far one can go tuning the system for measuring the accurate latency , these are the learnings made while measuring the latency using the DPDK skeleton application and i40e PMD.
Various kernel boot options , kernel system settings and secret i40e PMD setting will be explained and how they can affect the latency.
These learnings can be leveraged by ecosystem to measure other DPDK application latency.
Reshma Pattan is as network software engineer at Intel, Ireland. She has 5+years of DPDK experience mainly contributed to Power Management, Pdump,Telemetry , Reorder, Latency libraries and SoftNIC PMD.
