How To Install libio-aio-perl on Ubuntu 18.04
Introduction
In this tutorial we learn how to install libio-aio-perl on Ubuntu 18.04.
What is libio-aio-perl
libio-aio-perl is:
IO::AIO module implements asynchronous I/O using whatever means your operating system supports. It is implemented as an interface to the libeio library: http://software.schmorp.de/pkg/libeio.html.
Asynchronous means that operations that can normally block your program (e.g. reading from disk) will be done asynchronously: the operation will still block, but you can do something else in the meantime. 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. Use an event loop for that (such as the L
In this version, a number of threads are started that execute your requests and signal their completion. You don’t need thread support in perl, and the threads created by this module will not be visible to perl. In the future, this module might make use of the native aio functions available on many operating systems. However, they are often not well-supported or restricted (GNU/Linux doesn’t allow them on normal files currently, for example), and they would only support aio_read and aio_write, so the remaining functionality would have to be implemented using threads anyway.
Although the module will work in the presence of other (Perl-) threads, it is currently not reentrant in any way, so use appropriate locking yourself, always call poll_cb from within the same thread, or never call poll_cb (or other aio_ functions) recursively.
There are three methods to install libio-aio-perl on Ubuntu 18.04. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
Install libio-aio-perl Using apt-get

After updating apt database, We can install libio-aio-perl using apt by running the following command:
sudo apt -y install libio-aio-perl
Install libio-aio-perl Using aptitude
If you want to follow this method, you might need to install aptitude first since aptitude is usually not installed by default on Ubuntu. Update apt database with aptitude using the following command.
sudo aptitude update
After updating apt database, We can install libio-aio-perl using aptitude by running the following command:
sudo aptitude -y install libio-aio-perl
