in reply to Is Performance Overrated?

I wonder if you would be able to be so complacent about the performance of your Perl scripts if the writers and maintainers of Perl itself had adopted your "performance is for suckers." attitude?

How much slower could your scripts run and still be within the realms of acceptability to your users?

    See, there’s a difference. perl is invoked hundreds of millions of times every day. It pays to microoptimise that. I doubt the scripts the OP writes get that sort of work-over.

    It’s always a matter of tradeoffs and diminishing returns in various forms of expenditure.

    Personally, I always try to write code that doesn’t do unnecessary work; this is mostly a question of cultivating algorithmic sensitivity and understanding how things work under the hood. But I only actually start worrying about performance when the performance gets worrisome.
