来源：互联网发布：资本主义灭亡知乎编辑：程序博客网时间：2024/05/16 16:15

测试环境：

CPU：Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz * 2
内存：64GB 1333 MHz
OS：CentOS release 6.7

Libzmq：
https://github.com/zeromq/libzmq
master分支最新代码，版本号 4.2.1

测试准备：

测试代码perf/inproc_thr.cpp
主要改动（具体改动见附录diff）pull、push分别绑定不同的core（2,3）
测试数据量message count为 200000000
