We use so much memory for implementing a tree for fast research of addresses using phonetics (28M addresses)... using Oracle (a big machine optimized by two DBA experts) was two slow for us (around 1 second per query)... A big improvement was obtained using special indexes (created by lucene) stored in SSD... but still to slow for us... so the only solution was to use a "special" tree all in memory.... just investigating if there is something else in the open source that could save us Weblogic licences.... -- Sebastian E.
