If you run out of memory the performance won't be so good. I was questioning the logic of using a tied file while holding all the output in memory. The OP didn't state the file sizes or performance requirements. But since you seem to be focused on performance wouldn't it perform better to read the file into an array? For larger files the tied file will only keep part of the file in memory so it will end up rereading the file many times.
