Tie::Cache::LRU::Array3pm

Usage

  use Tie::Cache::LRU::Array;
  tie %cache, 'Tie::Cache::LRU::Array', 500;
  ...the rest is as Tie::Cache::LRU...

Overview

This is an alternative implementation of Tie::Cache::LRU using Perl arrays and built-in array operations instead of a linked list. The theory is that even though the algorithm employed is more expensive, it will still be faster for small cache sizes (where small <= ??) because the work is done inside perl (ie. higer big O, lower constant). If nothing else, it should use less memory.
