Problem
A NAS share is mounted with settings optimized for general office files rather than large sequential media, reducing predictable throughput during editing.
Solution
Root Cause / Diagnostic:
Default NAS SMB configurations are tuned for general office files, employing small I/O buffer windows, aggressive synchronous write locking, and conservative protocol timeouts. When handling large, multi-gigabyte video files, these office-centric settings create unnecessary packet fragmentation and protocol overhead, reducing sequential throughput.
Actionable Fix:
1. SMB Media Streaming Configuration: In `smb.conf`, optimize socket options and buffer parameters for large sequential transfers (`socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=1048576 SO_SNDBUF=1048576`, `aio read size = 1`, `aio write size = 1`).
2. Asynchronous I/O Activation: Ensure asynchronous I/O (`aio`) and Fruit optimizations are enabled to allow smooth streaming of massive media files.
3. Sequential Throughput Benchmark: Benchmark large file read/write performance using Blackmagic Disk Speed Test to confirm sustained speeds exceed 900MB/s over 10GbE.
Pro Tip:
Default NAS settings are designed for Word documents, not 100GB video files; tune your NAS Samba settings for large sequential transfers to unlock maximum streaming performance.
