node.js - 无法达到 60K 到 1L 的并发连接连接数

Question

我在 AWS t2.xlargeec2 机器上的 NodeJS 上运行了套接字 IO 应用程序。我试图在t2.xlargeAWS 机器上达到 60K 并发端口。

我做了以下更改ec2：

/etc/sysctl.conf文件：

net.ipv4.ip_local_port_range = 12000 65535
fs.file-max = 1048576

/etc/security/limits.conf

*           soft      nofile     1048576
*           hard      nofile     1048576
root        soft      nofile     1048576
root        hard      nofile     1048576 

我正在使用artillery负载测试。当我们达到约 30K 端口时，artillery开始显示错误：

我使用netstat -anp|grep ESTABLISHED | grep -w 80 > ports命令来检查打开的并发端口。
