A. Just curious, are these servers performing any work besides purely serving content? Eg user auth, album art, show description, etc?
B. What’s the current biggest bottleneck preventing higher throughout?
C. Has everything been up streamed? Meaning, if I were to theoretically purchase the exact same hardware - would I be able to achieve similar throughout?
(Amazing work by the way in these continued accomplishments. These posts over thr years are always my favorite HN stories.)

I'm eagerly awaiting Gen5 PCIe NICs and Gen5 PCIe / DDR5 based servers :) c) Yes, everything in the kernel has been upstreamed. I think there may be some patches to nginx that we have not upstreamed (SO_REUSEPORT_LB patches, TCP_REUSPORT_LB_NUMA patches).
