In my understanding (http://doc.dpdk.org/spp-18.02/setup/performance_opt.html) I should be able to "Use the isolcpus Linux kernel parameter to isolate them from Linux scheduler to reduce context switches. It prevents workloads of other processes than DPDK running on reserved cores with isolcpus parameter." but can't make it work. Which is the correct way to bind DPDK threads to isolated cpus?
