Optimization used to have a very noticeable impact on search speed prior to some index format changes from quite a while ago.
At this point the effect is much less noticeable, but the thing optimize does do is reclaim resources from deleted documents. If you have lots of deletions, it's a good idea to periodically optimize, but in that case it's often done pretty infrequently (once a day/week/month) rather than as part of any ongoing indexing process.
