If there isn't enough memory to cache the index in RAM, then your bottleneck could be from retrieving stored fields from disk. Distributed search will make this much worse because you have 2 JVMs eating up memory instead of one, further lowering the cache hit ratio of the OS disk cache. With a 2 CPU machine, a single Solr index is advisable, esp for web traffic where there will be plenty of requests to keep both CPUs busy. -Yonik
