[...] It would probably help if you could post some benchmarks of what your current search response times are (from the Solr back-end, and not from any front-end in front of it), and what your desired response times are. You could use Apache bench, and or JMeter for this. As a data point, while our index size/no. of documents is smaller (~40GB/3.6 million documents), we are seeing a mean response time/request of ~120ms for numeric fields, at 50 simulated simultaneous connections, with a single Solr server having 8 ~2GHz cores, and 12GB RAM. This measure however, *is* influenced by the effects of Solr caching. Solr is close to a factor of 10 faster than our front-end, even though that is pulling almost everything from Solr. So, we are happy on that front :-) Regards, Gora
