Thanks Walter for your inputs. Our use case and performance benchmark requires us to invoke optimize.
Here we see a chance of improvement in performance of optimize() if invoked in parallel. I found that if* distrib=false *is used, the optimization will happen in parallel. But I could not find a way to set it using HttpSolrServer/CloudSolrServer. Also with the parameter setting as given in my mail above does not seems to work. Please let me know in what ways I can achieve the parallel optimize on SolrCloud.
