获取更多连接

由于系统限制网络接口最多连接 64k，您可以设置 --interface 以绑定更多接口来增加连接数

nostr-bench connect 'ws://127.0.0.1:8080' --interface 192.168.0.2 --interface 192.168.0.3

增加资源使用限制

Linux

ulimit -n 1000000
sudo sysctl -w net.ipv4.ip_local_port_range="1025 65534"

Mac OS

ulimit -n 1000000
# sysctl net.inet.ip.portrange
sudo sysctl -w net.inet.ip.portrange.first=1025
sudo sysctl -w net.inet.ip.portrange.last=65534
