iob_prefetch ā€” prefetch data for I/O batch


#include <iob.h>

void iob_prefetch(io_batch* b,uint64 n);


iob_prefetch makes sure the next n bytes are in memory.

This is useful when serving large files over the network concurrently. Prefetching the data can then reduce hard disk head movement and enhance throughput.
