```sh
cargo install nostr-bench nostr-bench --help
```
Since the system limits a network interface to connect up to 64k, you can set --interface
to bind more interface to increase the number of connections
sh
nostr-bench connect 'ws://127.0.0.1:8080' --interface 192.168.0.2 --interface 192.168.0.3`
Linux
sh
ulimit -n 1000000
sudo sysctl -w net.ipv4.ip_local_port_range="1025 65534"
Mac OS
```sh
ulimit -n 1000000
sudo sysctl -w net.inet.ip.portrange.first=1025 sudo sysctl -w net.inet.ip.portrange.last=65534
```
