### Network optimizations {#network-optimizations}
To optimize the network settings for better performance, execute the following commands:
```bash
MaxExpectedPathBDP=8388608
sudo sysctl -w net.core.rmem_max=$MaxExpectedPathBDP
sudo sysctl -w net.core.wmem_max=$MaxExpectedPathBDP
sudo sysctl -w net.ipv4.tcp_rmem="4096 87380 $MaxExpectedPathBDP"
sudo sysctl -w net.ipv4.tcp_wmem="4096 16384 $MaxExpectedPathBDP"
sudo sysctl -w net.ipv4.tcp_slow_start_after_idle=0
```

These changes do not persist across system restarts. To apply them automatically on boot, add the following in `/etc/sysctl.d/local.conf`:
```bash
net.core.rmem_max = 8388608
net.core.wmem_max = 8388608
net.ipv4.tcp_rmem = 4096 87380 8388608
net.ipv4.tcp_wmem = 4096 16384 8388608
net.ipv4.tcp_slow_start_after_idle = 0
```
