noun
Computing term for the time required to retrieve data from a storage device or memory.
このハードディスクの呼び出し時間は非常に短い。
The access time of this hard disk is very short.
呼び出し時間が長いと、システム全体のパフォーマンスが低下する。
If the access time is long, the overall system performance degrades.
Synonymous loanword; more common in casual tech conversation, while 呼び出し時間 is a native Japanese term often seen in formal documentation.
Compound of 呼び出し (calling out, summoning) and 時間 (time), literally 'calling-out time'. The computing sense is a calque of English 'access time'.
