> I think 15M random read IOPS is actually quite fast
680x NVMe SSDs over 68 storage servers (so 68 CPUs) for just 15M (or 25M, tuned) random read IOPS is pretty underwhelming. The use cases where 3FS (or some other custom designs) shine are more like, 200M random read IOPS with 64 servers each with 8 PCIe gen 4 NVMe SSDs (512x SSDs in total).
