Direct I/O

Turkish equivalent: Doğrudan G/ÇDomain: Operating Systems

An I/O mode that bypasses or reduces use of the operating-system page cache so applications interact more directly with storage buffers.

Boundaries

Direct I/O reduces page-cache involvement but does not guarantee zero copy, lower latency, or better throughput for every workload.

  • Page Cache
  • Zero Copy
  • Memory-Mapped I/O
  • Storage
