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).
