This is extremely useful for programs that need to stay +interactive even when doing heavy I/O (GUI programs, high performance +network servers etc.), but can also be used to easily do operations in +parallel that are normally done sequentially, e.g. stat'ing many files, +which is much faster on a RAID volume or over NFS when you do a number +of stat operations concurrently. + +While most of this works on all types of file descriptors (for example +sockets), using these functions on file descriptors that support +nonblocking operation (again, sockets, pipes etc.) is very inefficient +or might not work (aio_read fails on sockets/pipes/fifos). Use an +event loop for that (such as the Event module): IO::AIO will naturally +fit into such an event loop itself. + +WWW: http://search.cpan.org/dist/IO-AIO/ |
