Magic xpa Cache (Magic xpa 2.x)

The basic assumption behind the need for caching is that the same data will be needed more than once. Therefore, if data can be re-fetched without performing disk I/O operations, overall performance will be enhanced.

Unlike general purpose disk caches that employ generic algorithms for their caching, the Magic xpa cache lets you fine-tune the cache according to your knowledge of the physical data and the nature of the project, and even on a user-by-user basis in a project.

The Magic xpa cache does not call any file manager as other hardware or software caching methods might. The Magic xpa cache therefore avoids the additional file manager overhead of traditional methods.
