 Hi Dpdk team,
   Can anyone please share tips to get better DPDK performance? 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 generation connections... but I don't get very consistent results.
   The same test application does not behave similarly on 2 PC's with same hardware configuration.But general observation is that, performance 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.
    The performance issue I am facing is the Packet Drop issue on the Rx side.
 Two PC's with exactly same hardware configuration, one PC drops packets after few hours, but in the other PC I don't observe packet drop
Highly appreciate a quick response
Regards,Anand Prasad
