PerlIO::buffersize - Set the buffersize of a handle
open my $fh, '<:buffersize(65536)', $filename;
This module sets the buffer-size of a filehandle to an other value than the default. This can only be done before the handle is used, as once the buffer has been allocated it can not be changed.
This modules does not have to be loaded explicitly, it will be loaded automatically by using it in an open mode. The module has the following general syntax:
:buffersize(size). The size can be any positive integer.
