Disabling file caching eliminates double-caching waste, but once data misses shared buffers it goes directly to the storage layer, requiring a sufficiently high hit rate; otherwise the cost of a miss may be amplified.

UnverifiedDouble buffering refers to the same data page existing simultaneously in both the OS page cache and shared buffers, resulting in duplicated memory usage and dilution of effective cache capacity.77% similarUnverifiedLossless memory solutions make a trade-off between storage cost and information fidelity that favors fidelity.75% similarUnverifiedIn cache-intensive, long-context, multi-turn agent workflows, the incremental cost of switching to a more powerful model is diluted by cache reads and does not necessarily mean costs double.72% similarUnverifiedThe delayed allocation strategy temporarily stores data in the in-memory page cache and defers physical space allocation until the data is flushed to disk, allowing the file system to find a sufficiently large contiguous area in one pass.71% similar
