ABSTRACT::  We present the motivation, design, implementation,
and performance evaluation of a UNIX kernel mechanism
capable of establishing fast in-kernel data pathways
between I/O objects.
A new system call, \fIsplice()\fP moves data asynchronously
and without user-process intervention to and from I/O
objects specified by file descriptors.
Performance measurements indicate improved I/O throughput
and increased CPU availability attributable to reduce
context switch and data copying overhead.
