How Does the Linux Page Cache Speed Repeated Home Server Reads?
The first read fills the page cache; repeated reads can avoid storage until memory pressure reclaims those cached pages.
Why Does Thumbnail Generation Drive High CPU and I/O on a Media NAS?
Tiny previews can require large source reads, image or video decoding, many small writes, and repeated metadata updates across a media library.
Why Do Random Reads Expose Latency Hidden by Sequential NAS Tests?
Sequential throughput reflects streaming efficiency; random reads reveal request delay, locality loss, cache misses, and per-file overhead.
How Does I/O Queue Depth Change Home NAS Throughput and Latency?
Queue depth helps a NAS use storage parallelism until outstanding requests become waiting work, raising latency even as total throughput improves.
Why Do Home NAS Transfers Slow After an SSD’s SLC Cache Fills?
An SSD's SLC cache accelerates short NAS writes, but sustained transfers can expose slower native NAND and competing internal data movement.
How Does Data Temperature Guide Storage Tiering in a Home NAS?
Data temperature guides SSD and HDD placement only when a home NAS observes sustained demand, limits migration overhead, and rechecks changing workloads.
What Changes When a Home NAS Stores VM Disk Images?
A home NAS storing active VM disk images handles mixed block I/O, flush semantics, sparse allocation, and snapshot dependencies—not just file throughput.
Why Can Extended Attributes Slow NAS File Migration?
Extended attributes slow NAS migration only when preservation, translation, or companion-file work accumulates across enough files.
