You can read Note:176135.1 to understand what optimze_index really
does and what is the difference between FULL and other modes. If You
can't afford waiting too long You can always execute optimize_index in
small batches by specifying maxtime parameter. As for performance it
really depends on how much inserts/updates did underlying documents
had (how much "suboptimal" index is).
