Hello Alexander,

I would definitely take a look at how much RAM each node has. You can adjust the max heap size in riak.conf by changing search.solr.jvm_options max heap size values from -Xmx1g to -Xmx2g or more. I’d also take a look at <>, which has links to Solr performance issues/factors and ways to monitor Solr.

You can get more statistical information for search by using `riak-admin stat show <statistic>`. Our documentation of these statistics is still in progress, but you can see what’s available for search here: <>.
