dpdk-redis

Fork from official redis-3.0.5, and run on the dpdk user space TCP/IP stack(ANS"Acceleted Network Stack"). For detail function, please refer to redis official website(http://redis.io//).

build and install

  • Download latest dpdk version from dpdk website, and build dpdk
$ make config T=x86_64-native-linuxapp-gcc
$ make install T=x86_64-native-linuxapp-gcc
$ export RTE_SDK=/home/mytest/dpdk
$ export RTE_TARGET=x86_64-native-linuxapp-gcc
  • Download ANS following the ANS wiki, build ans and startup ans
$ git clone https://github.com/ansyun/dpdk-ans.git

  • dpdk-redis vs official redis benchmark results

official redis test was executed using the loopback interface. benchmark results.

dpdk-redis test was executed using the 82599ES interface. If run more redis-benchmark, could get higher performance.

Notes

  • Shall use the same gcc version to compile your application.
  • In order to improve ANS performance, you shall isolate ANS'lcore from kernel by isolcpus and isolcate interrupt from ANS's lcore by update /proc/irq/default_smp_affinity file.
  • You shall include dpdk libs as below way because mempool lib has attribute((constructor, used)) in dpdk-16.07 version, otherwise your application would coredump.
