I posted earlier about being unable to get it to work on Fedora 14, but have it working on CentOS 6.4. Here is my hardware - Intel Xeon E5-2690 (8 physical, 16 virtual) 64 Gbyte DDR3 memory Intel 82599EB-SPF dual port 10GE interface CentOS 6.4 (2.6.32-358.6.1.el6.x86_64) The 82599 is in a 16x PCI-e slot. I have it attached to an IXIA box. I have been running the app 'testpmd' in iofwd mode with 2K rx/tx descriptors and 512 burst/mbcache. I have been varying the # of queues and unfortunately, I am not seeing full line rate. I have CentOS booted to runlevel 3 (no X windows) and have turned off (I think) all of the background processes I can. I am seeing about 20-24% droppage on the receive side. It doesn't seem to matter the # of queues. Question 1: Is 'testpmd' the best application for this type of testing? If not, which program? Or do I need to roll my own? Question 2: I have blacklisted the Intel i350 ports on the motherboard and am using ssh to access the platform. Could this be affecting the test? Thoughts? Thanks, Patrick
