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.

Can't use RDMA without MOFED properly on Nvidia cards.
