Simple performance mesurement

[s5uishida]

Hi,

It may not be very meaningful on Virtulabox VMs, but in order to evaluate the relative performance of several UPFs, I briefly measured the performance of UPFs.

https://github.com/s5uishida/simple_measurement_of_upf_performance

xdp_attach_mode was set to generic, but I expect that the performance will be significantly improved when set to native or offload for the real devices.

FYI.

Hi @s5uishida

Great job!

BTW vertio-net was mentioned. Kind of typo? Should be virtio-net?

Why don't you configure native attach mode on eUPF during tests? Seems like virtio-net should support XDP. With the native mode these tests would be more indicative :)

Hi @pirog-spb

Thank you very much for pointing this out. I corrected to virtio-net.

BTW, when I set the virtualbox VM's virtio-net to native and started it, the following error occurred.

If you know how to deal with this, I would be very grateful if you could let me know.

A related URL would also be very helpful.

Best regards,

Hi @pirog-spb

Thank you very much for your information.

I will try it.
