Detailed Description

LCStore implementation which stores data as a collection of CDB files in the directory given by $wgCacheDirectory.

If $wgCacheDirectory is not set, this will throw an exception.

Profiling indicates that on Linux, this implementation outperforms MySQL if the directory is on a local filesystem and there is ample kernel cache space. The performance advantage is greater when the DBA extension is available than it is with the PHP port.
