Hi - I posted this problem but no response, I guess I need to post this in the Solr-User forum. Hopefully you will help me on this.
We were running Solr 1.3 for long time, with 130 cores. Just upgrade to Solr 1.4, then when we start the Solr, it took about 45 minutes. The catalina.log shows Solr is very slowly loading all the cores. We did optimize, did not help at all. I run JConsole to monitor the memory. I notice the first 70 cores were loaded pretty fast, like in 3,4 minutes. But after that, the memory went all way up to about 15GB (we allocated 16GB to solr), and it slows down right there, slower and slower. We use concurrent GC. JConsole shows only ParNew GCs kicked off, but it doesnt bring down the memory. With Solr 1.3, all 130 cores loaded in 5,6 minutes. Please let me know if there is known memory issue with Solr 1.4. Or is there something (configuration) we need to tweak to make it work efficiently in 1.4? thanks -- 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-tp1608728p1608728.html Sent from the Solr - User mailing list archive at Nabble.com.
