  - Supports unix socket connection for even better performance on a single machine.
  - Supports configurable compression for memory savings. Can choose between gzip, lzf and snappy and can change configuration without flushing cache.
  - Uses transactions to prevent race conditions between saves, cleans or removes causing unexpected results.
+ - Supports a configurable "auto expiry lifetime" which, if set, will be used as the TTL when the key otherwise wouldn't expire. In combination with "auto expiry refresh on load" offers a more sane cache management strategy for Magento's `Enterprise_PageCache` module.
