LibreQoS

VM or physical server. Physical server will perform better and better utilize all CPU cores.
One management network interface, completely separate from the traffic shaping interfaces. Usually this would be the Ethernet interface built in to the motherboard.
Dedicated Network Interface Card
NIC must have two or more interfaces for traffic shaping.
NIC must have multiple TX/RX transmit queues. Here's how to check from the command line.
- Known supported cards:
  - NVIDIA ConnectX-4 MCX4121A-XCAT
  - Intel X710
  - Intel X520
Ubuntu Server 22.04 or above recommended. All guides assume Ubuntu Server 21.10 or above. Ubuntu Desktop is not recommended as it uses NetworkManager instead of Netplan.
Kernel version 5.14 or above
Python 3, PIP, and some modules (listed in respective guides).
Choose a CPU with solid single-thread performance within your budget.
- Recommendations for 10G+ throughput:
  - AMD Ryzen 9 5900X
  - Intel Core i7-12700KF
Choose a CPU with solid single-thread performance within your budget. Generally speaking, any new CPU above $200 can probably handle shaping up to 2Gbps.
