Hello,
We recently began migrating a few of our applications from 1.3 to 1.4 in
order to take advantage of the replication and performance improvements.
In practice however, we are noticing that our instances which make use
of LocalSolr have experienced some performance degradation from 1.3
I don't know exactly how the local solr stuff currently works (it's
not currently part of Solr), but it's possible to get worse memory
performance if you're not careful. Solr and Lucene now do per-segment
searching and sorting in a single index... and that means fieldcache
entries populated at
