that is exactly what happend, sorry for wrong numbers,  now it looks as it should:

java -version
Java(TM) SE Runtime Environment (build 1.6.0-beta2-b83)
Java HotSpot(TM) Client VM (build 1.6.0-beta2-b83, mixed mode, sharing)

java -server -Xbatch org.apache.solr.util.BitSetPerf 1000000 50 10000 union 3000 bit
ret=0
TIME=21966

java -server -Xbatch org.apache.solr.util.BitSetPerf 1000000 50 10000 union 3000 open
ret=0
TIME=19832

I measured also on different densities, and it looks about the same. When I find a few spare
minutes will make one PerfTest that generates gnuplot diagrams. Wold be interesting to see
how all key methods behave as a function of density/size.
