In my personal experience: ramBufferSizeMB=8192 helps to keep many things in RAM and to delay Index Merge forever (I have single segment 10G with almost 100 mlns docs after 24 hours)
Heavy I/O was a problem before, and I solved it -----Original Message----- From: Archon810 [mailto:archon...@gmail.com] Sent: August-14-09 6:21 PM To: solr-user@lucene.apache.org Subject: Which server parameters to tweak in Solr if I expect heavy writes and light reads? I am facing scalability issues designing a new Solr cluster and I need to master to be able to handle a relatively high rate of updates with almost no reads - they can be done via slaves. My existing Solr instance is occupying a huge amount of RAM, in fact it started swapping at only 4.5mil docs. I am interested in making the footprint as little as possible in RAM, even if it affects search performance. So, which Solr config values can I tweak in order to accomplish this? Thank you. P.S.
