- Replace defaults with explicit optimized NFSv3 options - noatime: eliminates 8M+ atime setattr calls during Syncthing scans - rsize/wsize=1048576: 32x larger transfer buffers (was 32KB) - timeo=14: 1.4s timeout instead of 60s (LAN, not WAN) - retrans=5: more retries since timeo is low Root cause: NFS server only supports NFSv3, and 'defaults' uses kernel-minimum rsize/wsize=32KB + atime updates on every read. Syncthing's 80K-file scans generated 52M getattr + 8M setattr RPCs. These options reduce metadata RPC overhead and increase data throughput.
