Network Programming with Perl

Summary

The IO::Poll module provides an interface to the system poll() call and can be used as an alternative to select() for multiplexing across multiple I/O handles. Compared with select(), poll() provides improved performance when multiplexing across a large number of handles and should be considered for servers that will have heavy loads. However, IO::Poll should be used with care when writing applications designed for portability, because it became a part of the standard I/O library only as of Perl version 5.6.
