Re: Hash references versus hashes: is there a performance hit?by philcrow (Priest) |

The real difference comes when you pass the hash to a sub. Then, large hashes are serialized as lists, while references are just a single scalar.
I'm not willing to guess what the performance of a simple lookup is. But, both of them have the hash the key which might be the dominant part of the process. Phil
