Hi Yonik, thanks for your reply. I entered a bug for this at : https://issues.apache.org/jira/browse/SOLR-2138
to answer your questions here: - do you have any warming queries configured? ----> no, all autowarmingcount are set to 0 for all caches - do the cores have documents already, and if so, how many per core? ----> yes, 130 cores total, 2,3 of them already have 1~2.4 million documents, others have about 50,000 documents - are you using the same schema & solrconfig, or did you upgrade? ----> yes, absolutely no change - have you tried finding out what is taking up all the memory (or all the CPU time)? ----> yes, JConsole shows after 70 cores are loaded in about 4 minutes, all 16GB memory are taken and rest of cores load extremely slow. The memory remain high and never dropped. We are in process to upgrade to 1.4.1 -- View this message in context: http://lucene.472066.n3.nabble.com/Upgrade-to-Solr-1-4-very-slow-at-start-up-when-loading-all-cores-tp1608728p1611030.html Sent from the Solr - User mailing list archive at Nabble.com.
