This talk is the latest updates on the progress of doing 10Gbit/s routing on standard hardware running Linux. The results are good, BUT to achieve these results, a lot of tuning is required of hardware queues, MSI interrupts and SMP affinity, together with some unsubmitted patches. I'll explain the concept of network hardware queues and why interrupt and SMP tuning is essential.
I'll present results from different hardware both 10GbE netcards and CPUs (current CPUs under test is AMD phenom and Core i7).
Many future challenges still exists, especially in the area of more easy tuning. A high knowledge level about the Linux kernel is required to follow all the details.
