As Otis mentioned, its obviously good to run Optimization once in a while
or when you are done with most of your heavy indexing operation. Its not
concern with the Disk Capacity rather with the IO and seeking in segements,
When comparably it has less segments to query the IO operation will be less
and so quick will be your query response.
Give it a go and come up with the stats.
Cheers!

Hi,
I don't remember last time I ran optimize. Sure, yes, things will work
faster if you optimize an index and reduce the number of segments, but if
you are regularly writing to that index and performance is OK, leave it to
Lucene segment merges to purge deletes.

Hi,
We have SolrCloud cluster (5 shards and 2 replicas) on 10 boxes. On some
of the boxes we have about 5 million deleted docs and we have never run
optimization since beginning. Does number of deleted docs have anything
to
do with performance of query? Should we consider optimization at all if
we're not worried about disk space?
Thanks!
