Thanks Yonik,
It uses a thread per request, simultaneously (up to any limit configured by the app server)
How can I change this setting then? I suppose it is to do with Jetty or Tomcat whichever hosts solr application, not through the solrconfig?
I still do not understand why sending 100 request (of same query) from 100 threads throws solr server to silence - is it because of the computational cost to deal with same query in 100 separate threads?
I noticed that disabling facet counts improves things a bit, but not significant.
Thanks in advance!
