We are also se= eing performance degradation in our packet processing application for about= ~3% with 17.02. When we browsed through mailing lists, we found a similar thread as mention= ed in this email subject from Cisco T-Rex. But the thread did not point to = any resolution instead they could fix it in their software. Before starting to figure out which commit of dpdk (git bisect) is causing = our application to degrade (which is tedious and slow), we are wondering th= at if the resolution for the T-Rex is shared in broad sense like which dpdk= api etc. That would really help.
