cliでopcacheを有効にしたほうがよいケースはあるか（デフォルト無効）
The opcache.enable_cli option enables PHP OPcache when running PHP scripts from the command line (using the php command). However, keep in mind that for PHP 5.x the OPcache extension works by storing cached opcodes in the memory of the current process. This is only useful when the process that's running PHP is going to be handling multiple requests that can reuse these opcodes, like in a web server or under FastCGI. For a process like the PHP CLI, which runs one "request" and exits, it just wastes memory and time.
