I can definitely attest to this. The really nice thing about the standard Solr/Jetty configuration is that its all there, Lucene+Solr+Jetty and you just turn it on and run, and after only minor tweaks to JVM and memory settings, its effectively production ready with a reliable master- slave configuration. The servers I run do about 30,000 + searches a day 95% are sub second on massive indexes. With SolrCloud and ZK, it does work out of the box, but explicitly said every where its not supposed to be in production until you configure and maintain your own external ZK ensemble. If it was simplified some what, I think a lot more people would migrate over to SolrCloud, but for now I can say we are not going in that direction.
