Much depends on how often the index is updated. If your index only changes, say, once a day then it's probably a good idea. If you're constantly updating your index, then I'd recommend that you do _not_ optimize.
Optimizing will create one large segment. That segment will be unlikely to be merged since it is so large relative to other segments for quite a while, resulting in significant wasted space. So if you're regularly indexing documents that _replace_ existing documents, this will skew your index. Bottom line: If you have a relatively static index the you can build and then use for an extended time (as in 12 hours plus) it can be worth the time to optimize. Otherwise I wouldn't bother.
