"Blazing-Fast Magic Beans"
summary
Solana’s validator client Agave claims real-world wins: a custom Agave-xdp XDP stack hitting 2.5M packets/sec with 27 context switches and zero page faults, io-uring storage that unpacks a 100 GB tarball nearly 3× faster, QUIC improvements (GRO, fragmentation fixes) in Quinn, and an eBPF-based ebpf profiler that captures off‑CPU waits and line‑level profiles. Public cluster shows >100k transactions/sec and a scheduler demo reaches >1M TPS; live comparison site flipd.market benchmarks against NASDAQ.
