Hi All, I have recently migrated from solr 1.4 to solr 4 and have done the basic changes required for solr 4 in solrconfig.xml and schema.xml. I have also rebuilt the index set for solr 4. We run optimize every morning at 4 am and we keep the index updates off during this process. Previously, with 1.4 - the optimization used to take around 20-30 mins per shard but now with solr 4, its taking 6-8 hours or even more.. I have also tested the optimize from solr UI and that takes 6-8 hours too.. The hardware is saeme and, we have deployed solr under WAS. There ar 4 shards and every shard contains around 8 - 9 Gig of data and we are using master-slave configuration with rsync. I have not enabled soft commit. Also, commiter process is scheduled to run every minute.
I am not sure which part I'm missing, do let me know your inputs please. Many Thanks in advance, Sandeep
