Perl module providing a mmap'ed cache

Cache::FastMmap uses the mmap system call to establish an interprocess shared memory cache. Its core code is written in C, which can provide significant performance compared to a Pure Perl implementation such as Cache::Mmap. It can handle rather large pages without the socket connection and latency of using full-fledged databases where long-term persistence is unnecessary.

Since the algorithm uses a dual-level hashing system (a hash is used to find a page, then another hash within each page to find a given slot), most get calls can execute in constant O(1) time. The system uses fcntl to handle concurrent access, but only locks individual pages to reduce contention. The oldest (least recently used) data is evicted from the cache first, making this cache implementation most suitable for cases when old data is unlikely to be searched.
