How to avoid packet drop

[Robert Clove]

Hi All,

I am running a tool that is a packet generator.
With that tool i am able to achieve line/link rate on my 1Gbps network.
I have two queries

Query 1) When i run the same tool on 10Gbps network i am able to achieve
only 5Gbps rate.( by network i mean i have two machines with Centos 6.4
connected back to back.)

Query 2) When i run the packet generator on the 1Gbps link or 10Gbps link i
see a packet drop by kernel ( result of tcpdump -i eth2).How can i minimize
the packet drop?


Thanks
Clove
