Hello Folks, I posted on this topic yesterday and didnt hear back, thought I'd try again, has anyone used the elasticsearch java jest library and done perf tests with it running under tomcat. We have a rest service that abstracts away the jest library and performs crud functionality against an elasticsearch cluster and we're currently having some issues with running out of operating system sockets/file descriptors during our load test when using this library within a very short period of time, before I make any major changes I plan to: 1. Tweak the associated httpclient connection manager configs 2. Tweak environment linux settings Finally if the above don't make a difference I plan to: 3) Rewrite the code using the elasticsearch java API instead Would love to hear from the community about any learning around perf tests around the library.

Hi Saikat, I have replied to you through our support but maybe it is not reached. Well first please create only one JestClient it is singleton and configure it as multi threaded. That is very much possibility why you are having too many open sockets errors. You can configure max open connections and per route connections if necessary. Please see [Changelog · searchbox-io/Jest Wiki · GitHub](https://github.com/searchbox-io/Jest/wiki/Changelog) v0.0.3 To see all in action check JestClientFactoryTest.multiThreadedClientCreation for sample usages.
