          Hi,

           

          Please recheck the different sysfs value you must set in step 5 in the community link.

          5. Configure the RFS flow table entries (globally and per core).

          Note: The functionality remains disabled until explicitly configured (by default it is 0).

           

          The number of entries in the global flow table is set as follows:

          /proc/sys/net/core/rps_sock_flow_entries

           

          The number of entries in the per-queue flow table are set as follows:

          /sys/class/net/<dev>/queues/rx-<n>/rps_flow_cnt

           

          For example:

          # echo 32768 > /proc/sys/net/core/rps_sock_flow_entries

          # for f in /sys/class/net/ens6/queues/rx-*/rps_flow_cnt; do echo 32768 > $f; done

           

           

          Thanks

          Marc

              Hi, March

               

               

              I have 32 queues on a device.

              I change the parameters:

              echo 32768 > /proc/sys/net/core/rps_sock_flow_entries

              for f in /sys/class/net/ens3f0/queues/rx-*/rps_flow_cnt; do echo 1024 > $f; done

              But it's not work for me.

              dmesg
