Hi all, English is not my native language, please excuse typing errors.
Now We have a platform like this: CPU: Intel Xeon E3-1275v3 @3.5Ghz DRAM: Samsung DDR3 4G * 2 OS: RHEL 6.4 x64 NIC: XL710 (4 ports * 10Gbps) Lan driver: i40e-1.4.25 We used this platform to run Smartbit RFC2544 testing with 'testpmd' of DPDK, and the result shows that the throughput can not achieve line rate (100%) from packet size 256 bytes to 1518 bytes, just 99.297%. The version of DPDK what we used is 2.2.0, and the testing command is: ./testpmd -c 0x3c -n 4 -- -i --nb-cores=4 --portmask=0xf Why is that? PS. We did not put a acceptable frame loss in our smartbit setting, just 0%, and we checked details of the test report, it shows that there is few frame loss (~0.001%) while running with 100% loading. Best regards, Leo,
