in thread Bug when undefining a large hash

Thanks for suggestions! Results:

"%hash = ();" appears to do much the same as undef(), at least, it creates the same long delay.

Iterating all the keys and deleting them is slower than undef, although not by much: around 16 secs as opposed to 14 secs for undef.

So, no solutions there, but thanks for the ideas.

    Frankly speaking that didn't surprise me. I just thought it was worth a try. I tried it myself on Redhat also with increased values up to 30_000_000 same results as you.
