Re: ConcurrentUpdateSolrClient threads
Hi. I'm wondering the same. Some "updateBean" takes a very long time, up to 130 000 ms. Typically it takes around 100 ms. I'm using 2 threads and a queue size of 30. Haven't figured out what the default thread size is? 0? -- Sent from: http://lucene.472066.n3.nabble.com/Solr-User-f472068.html
