This describes simple performance measurements of several open source UPFs by using the traffic generator TRex as the performance measurement tool and Simple PFCP Client as the PFCP simulator. This was measured on the VMs on Proxmox VE. For other measurement results, please see Performance Measurement.
Note. Performance measurement results are highly dependent on the measurement conditions. These results are only examples of results under certain measurement conditions. And this is a very simple measurement, and according to this comment, it doesn't seem to make much sense to measure between VMs. I hope it will serve as a reference for a simple configuration when measuring on real devices.

I will easily measure the performance of several open source UPFs by using TRex as the traffic generator and Simple PFCP Client as the PFCP simulator. Note that this configuration is implemented with Proxmox VE VMs.
The following minimum configuration was set as a condition.
- One PFCP client, TRex and DUT (UPF)
The built simulation environment is as follows.
Simple PFCP Client, TRex used are as follows.
- Simple PFCP Client (2025.01.16) - https://github.com/s5uishida/simple_pfcp_client

These measurement results show that eUPF has relatively outstanding performance even on Proxmox VE VM. Also, Open5GS shows significantly higher performance when measured with srsRAN. This suggests that the measurement environment, condition and tools have a large impact on the measurement results.
If measuring using virtual machines, it would be better to measure on VMs on a hypervisor such as Proxmox VE. Also, it is good to select VirtIO as the network interface to ensure that the network does not become a bottleneck in the measurement.
It is very simple mesurement and may not be very meaningful when measuring between virtual machines, but it may be a little helpful when comparing the relative performance of UPF. I would appreciate it if you could use this as a reference as a configuration example when measuring with real devices.
I simply measured the raw communication performance between VM-TG and VM-DUT. This is a measurement of the N6 interface and therefore does not include communication over GTP-U.

I would like to thank all the excellent developers and contributors who developed these great systems and tools.
- [2025.01.20] Changed eUPF measurement to those measured using the binary that does not output kernel logs for debugging.
- [2025.01.17] Initial release.
