Hi, We're experiencing slow startup times of searchers in Solr when containing a large number of documents.
We use Solr v4.0 with Jetty and currently have 267.657.634 documents stored, spread across 9 cores. These documents contain keywords, with additional statistics, which we are using for suggestions and related keywords. When we (re)start Solr on one of our servers it can take up to two hours before Solr has opened all of it's searchers and starts accepting connections again. We can't figure out why it takes so long to open those searchers. Also the CPU and memory usage of Solr while opening searchers is not extremely high. Are there any known issues or tips someone could give us to speed up opening searchers? If you need more details, please ping me. Best regards, Marcel Bremer Vinden.nl BV
