I= have tried to run DPDK test applications on various PC configurations with= different CPU Speeds, RAM Size/Speed and and PCIex16 2nd and 3rd generatio= n connections... but I don't get very consistent results. =C2=A0=C2=A0 The same test application does not behave similarly on 2 PC's = with same hardware configuration.But general observation is that, performan= ce is better on Intel motherboard with 3rd generation PCIe slot. When tried= on Gigabyte motherboard (even with higher CPU and RAM speeds), performance= was very poor. =C2=A0=C2=A0=C2=A0 The performance issue I am facing is the Packet Drop iss= ue on the Rx side. =C2=A0Two PC's with exactly same hardware configuration, one PC drops packe= ts after few hours, but in the other PC I don't observe packet drop Highly appreciate a quick response Regards,Anand Prasad =20
