In order to do that we isolated the dpdk application cores and disabled hyperthreading for those cores. But sporadically we encounter misses over the interface. We are running on a single socket cpu with 44 hyperthreaded cores. we are using 5 cores for the dpdk application (which is in fact 10 since hyperthreading is disabled). My guess is that probably GC (garbage collection) running from the kernel and perhaps over the isolated threads causing the misses. Is there a way to solve this issue? Is there a way to isolate cores for kernel processes/threads? Thanks in advance, Shirley.
