We are experiencing slowness during reloading/resubmitting index from Database to the master.
We have two environments: QA and Prod. The slowness is happened only in Production but not in QA. It only takes one hours to reload 2.5Mil indexes compare 5-6 hours to load the same size of index in Prod. I checked both the config files in QA and Prod, they are all identical, except: In QA: <unlockOnStartup>false</unlockOnStartup> In Prod: <unlockOnStartup>true</unlockOnStartup> I believe that we use "http" protocol reload/submit the index from Database to Solr Master. I did test copying big files thru network from database to the solr box, I don't see any issue. We are running solr 1.2 Any inputs will be much appreciated.
