That's great information. Thanks for all the help and guidance, its been invaluable.
Thanks Ben -----Original Message----- From: Erick Erickson [mailto:erickerick...@gmail.com] Sent: 26 March 2012 12:21 To: solr-user@lucene.apache.org Subject: Re: Simple Slave Replication Question It's the optimize step. Optimize essentially forces all the segments to be copied into a single new segment, which means that your entire index will be replicated to the slaves. In recent Solrs, there's usually no need to optimize, so unless and until you can demonstrate a noticeable change, I'd just leave the optimize step off. In fact, trunk renames it to forceMerge or something just because it's so common for people to think "of course I want to optimize my index!" and get the unintended consequences you're seeing even thought the optimize doesn't actually do that much good in most cases. Some people just do the optimize once a day (or week or whatever) during off-peak hours as a compromise.
