This optimization enables Google's TCP BBR congestion control algorithm and TCP Fast Open.
|
|
</p>
|
|
<p className="mb-4">
|
|
<strong>Why it's important:</strong> TCP BBR can significantly improve network throughput and reduce latency, especially on long-distance or congested networks. TCP Fast Open reduces connection establishment time, improving the speed of short-lived connections. These optimizations are particularly beneficial in virtualized environments where network performance is crucial for overall system responsiveness.

This optimization configures APT (Advanced Package Tool) to use IPv4 exclusively.
|
|
</p>
|
|
<p className="mb-4">
|
|
<strong>Why it's important:</strong> Forcing APT to use IPv4 can resolve issues in environments where IPv6 is not properly configured or is causing slowdowns. This ensures more reliable package management operations, which is crucial for maintaining and updating your Proxmox VE system. It's particularly useful in networks where IPv6 connectivity might be unreliable or not fully supported.

This optimization installs Open vSwitch, a production quality, multilayer virtual switch.

|
|
<strong>Why it's important:</strong> Open vSwitch provides advanced networking capabilities for virtualized environments. It allows for more flexible and powerful network configurations, including support for VLAN tagging and trunking, advanced traffic shaping, and Quality of Service (QoS) capabilities. This is particularly beneficial for complex virtualization setups where fine-grained control over network traffic is required.

<p className="mb-4">
|
|
<strong>Why it's important:</strong> Proper configuration of network interfaces can significantly improve network performance, reduce latency, and increase stability. This is particularly important in virtualized environments where multiple VMs and containers share network resources. Optimizations like increasing the TX queue length can help prevent packet drops under high load.
