Add the option to your config file uses in the build of DPDK and set the value to ?y? instead of ?n?. Example: edit or copy say defconfig_x86_64-native-linuxapp-gcc and add something like this; CONFIG_RTE_LIBRTE_MEMPOOL_DEBUG=y Then rebuild DPDK using something like ?make install T=x86_64-native-linux-gcc -j' > However, I don't know how to use it. > > Is there any reference? > > Intuitively, as the number of rings are increase, I think the contention > happened frequently. > So, to avoid this, is increasing CONFIG_RTE_MEMPOOL_CACHE_MAX_SIZE one > solution? > > > Thanks, > Junguk
