Hi Will, How many keys will your hashes contain?
The main memory wastage with hashes isn't due to the size of what you keep in them but the number of keys. If you are using integers as keys, why not just use an array? Bare in mind that the 'hashspace' is shared between your hashes, so if you have a lot of hashes with only a relatively small number of entries (i.e. hundreds rather than thousands) you might want to look at using Binary::Tree::Dictionary - something I wrote when I needed a lot of low memory hash/dictionarys for relatively small data sets in a perl daemon.
