Great. Now we could gain detailed insights into how our system is behaving in real time, which is invaluable for troubleshooting and optimizing performance. For those who just heard eBPF, there is the fun-damental source about it [0].

Nice nice!

Btw, I'm wondering if OFED and/or DPDK are also still used, and if they're still used for fast packet pushing.

I think there must be still some corp frameworks that do use it extensively, but it's just not heard all that much about.

Some examples, (Broadcom) Vmware NSX-T gateways, Alivaba used to use it, and a lot of extreme HFT use it too, mostly to reduce latency and manipulate tcp.
