dino has asked for the wisdom of the Perl Monks concerning the following question:

Hi, what are the issues with perl file io and linux that make mutiple readlines so much slower than the equiv read? I've heard from a associate that perl file io is broken under linux, and wondered if it was true. Are there any known fixes appart from reinventing the wheel and replacing readline with the equiv reads? Is the linux kernel version relevant, and would using sfio make much difference? Regards dino
