Try running with 4GB heaps if you can. On recent JVMs -- but don't use 1.6.0_18! -- you can have the JVM compress 64 bit object references into 32 bits. This will save heap at minor performance cost. Add '-XX:UseCompressedOops' to HBASE_OPTS in hbase-env.sh. For more information on compressed OOPS: http://wikis.sun.com/display/HotSpotInternals/CompressedOops Also see this page on the HBase wiki for some related information: http://wiki.apache.org/hadoop/PerformanceTuning, the section "HBase JVM and GC" Hope this helps, - Andy
