OrientDB Improves Performance Through Defrag

The problems I found with the HOLES were that small spaces aren't reused at all and huge defragmentation was present. This caused a global slowness and the growth of the database on disk (in some cases many times the original size). After 2 weeks of work I've published in the SVN and maven the new version of the OrientDB storage with: In-line defrag: something like some File Systems already do by joining small holes all together. In-line defrag works while the database is online and in use Improved the management of small changes to records 2 configurable strategies of how to find the best hole to join during defrag process configurable hole distance to decide when to join multiple holes all together
