NAME

rt26188 - benchmark speed for keys() on empty hashes

DESCRIPTION

If you have an empty hash, the speed of keys() depends on how many keys the hash previously held.

For global hashes, getting the count for previously big hashes was substantially slower than for lexical hashes.

This test checks that the speed difference for getting the number or list of keys from an empty hash is about the same (< 25%) for lexical and global hashes, both previously big and small.

REFERENCE

This test tests against RT ticket #26188
