My first suspect here is that you don't have enough RAM for your index size. * How many total docs is Solr handling (all cores)? * What is the total size on disk of all your cores? * How much RAM does the machine have? * What is the java max heap? Here is some additional information on memory requirements for Solr: https://wiki.apache.org/solr/SolrPerformanceProblems#RAM When Alessandro asked about the load on Solr, the hope was to find out your *rate* of indexing and querying, not the load average from the operating system. Indexing requires a fair amount of heap memory and CPU resources. If your heap is too small, then Java might have to work extremely hard to free up memory for normal operation. Thanks, Shawn
