FYI there's ongoing discussion about whether this deprecation may have been a bad idea, and it's looking like it might get undeprecated again. See P2327. On the other hand, these...

Can you tell us more about your hardware and software configuration? On a well-tuned system the runtime of both of those functions should be tiny (probably

2000ns for `ef_eventq_poll()` does seem extremely high. You didn't answer my question about your hardware and software setup. I think my best guess at this stage is that you're running...

I'm kinda busy today, so I haven't thought as much about possible causes this time: 2000ns when using a Xilinx NIC is entirely unexpected. Is it possible that you have...

You don't say it explicitly, but the only way I can imagine that code partially working is if you're running `udp_send()` and `feedback()` on two different threads concurrently. That's incorrect:...

> By the way, if I want to sent packets with Stream Transfer, which transmit should I use? PIO? CTPIO? Will it affect the latency if I process events synchronously...

> I don't understand why ef_vi_transmit_space() always gets 0 after I run the app for a while I don't have any good ideas, but are you determining that it's 'stuck'...

We do not publish benchmarks, sorry. The best performance results will be obtained with a Xilinx/Solarflare NIC, since the AF_XDP compatibility layer used for other NICs is quite costly. Support...

Hi there! Yes, those "Kernel" numbers are using ordinary BSD sockets through the kernel stack, on a Solarflare X2522-25G NIC. The full hardware spec is given in section 2.4 of...

I got it building and loading with the instructions at https://docs.darlinghq.org/wsl-build.html with the following tweaks: - We require that the kernel config file be the usual `./.config`, so copy `Microsoft/config-wsl`...
