I'd like to a read potentially large files (a zsh script file) into an array fast. It is not uncommon for a GNU autoconf configure script to be tens of thousands of lines long. (As an example, The zsh configure script is over 20,000 lines long). I know about redirecting input in a loop and/or alternatively using "read" in a loop. But for a large file this tends to be slow. As a result, both bash and zsh have a mechanism for doing this faster than using a read loop. For zsh the speed difference was 0.189 seconds (to load zsh and the module and read) versus over a minute. For bash the difference in speeds is, I believe, even greater. So what's the fastest way to large read a file into an array?
