How are you indexing? It sounds like you may be sending one document at a time. Also, another common mistake is to send commits from the client, you should either set your autocommit intervals up in solrconfig.xml or, perhaps, send one (and only one) commit at the very end of the entire indexing job.
Throughput is sensitive to the number of docs you send to Solr at once, see: https://lucidworks.com/blog/2015/10/05/really-batch-updates-solr-2/ Best, Erick On Thu, Aug 18, 2016 at 2:24 AM, kshitij tyagi <kshitij.shopcl...@gmail.com> wrote: > how to shrink solr container thread pool?? > > On Thu, Aug 18, 2016 at 2:53 PM, kshitij tyagi <kshitij.shopcl...@gmail.com> > wrote: > >> refcount 171 is seen when i reindex a number of documents simultaneously? >> what does this means?
