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):

These numbers improved significantly after we increased ramBufferSizeMB to
1024, here is the full solrconfig.xml:

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
