Hello, I am using the new SOLR 3.1 for a 2.6 Gb, 1MM documents index. Reading the forums and the archive I learned that SOLR and Lucene now manage commits and transactions a bit differently than in previous versions, and indeed I feel the behavior has changed.
Here's the thing: committing a few 100s documents is consistently taking about 12 minutes of pure CPU fury on a 6168 AMD Opteron processor. Here is a log of the commit (taken from INFOSTREAM.txt): http://pastebin.com/1rFK3Fs1 These numbers improved significantly after we increased ramBufferSizeMB to 1024, here is the full solrconfig.xml: http://pastebin.com/M1Tw0ATe Does these numbers look normal to you? The index is being used for searching while the commit takes place (about 1 search per second). Thanks in advance, Santiago
