Good morning,
I have been playing with this code now for about 2 weeks. 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
