100G is boring, so I went 200G instead on the rx side. Implemented zc send in the test app (kperf) as well (io_uring already supports this). Single CPU thread, maxes out 200G link as well. See below for basic details:

@axboe when you say 200G it's not gbps because in the link says 96gbps. what's 200G and are you trying to just make cpu 100 percent? sorry for my ignorance

@thejvmbender Not sure what link you're referring to, but it's 98.4 and 98.6, so 197Gbps in total. Where's the 96 from?

@axboe link in the first post, i read as 98 and 96 but it was actually 98.6 🤓 I don't have my glasses sorry, so 200g means gbps 😇 thank you
