We are on Solr 4.10.3. Got 2 load balanced RedHat with 16 GB memory on each. Memory assigned to JVM 4 GB, 2 Shards, total docs 60 K, and 4 replicas.

If older-style master/slave, then "add more slaves". Solr request processing scales pretty linearly with the number of replicas (or slaves). Note that this is _not_ adding shards (assuming SolrCloud). You usually add shards when your response time under light load is unacceptable indicating that you need fewer documents in each shard. Biony's question needs to be answered before any but the most general advice is possible, what is your setup? What version of Solr? How many docs? How many shards? etc. Best, Erick On Thu, Feb 4, 2016 at 7:06 AM, Binoy Dalal <binoydala...@gmail.com> wrote: > What is your solr setup -- nodes/shards/specs? > 7221 requests/min is a lot so it's likely that your solr setup simply > isn't able to support this kind of load which results in the requests > timing out which is why you keep seeing the timeout and connect exceptions. > > On Thu, 4 Feb 2016, 20:30 Tiwari, Shailendra < > shailendra.tiw...@macmillan.com> wrote: > >> Hi All, >> >> We did our first load test on Search (Solr) API, and started to see >> some errors after 2000 Users.
