Everything you are describing smells like some kind of Disk/IO throttling behavior external to Solr.
Nothing you've identified below should be particularly "slow" and it certainly shouldn't get orders of magnitude slower for subsequent SolrCores in rapid succession, even as those cores are smaller then the cores that came before them. Are you absolutely certain the node/OS/host-vm you are running on isn't imposing / hitting any sort of Disk rate limiting ? -Hoss http://www.lucidworks.com/ --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@solr.apache.org For additional commands, e-mail: dev-h...@solr.apache.org
