Robin,
1) it must be debug build of drlvm;
2) syntax is -Xstats:[1|2|3] , the number denotes detalization level.
Actually this options gives various *statistics* for run, rather than
performance data or profile. E.g. number of particular byte ops
performed, exceptions thrown/caugth, most frequently allocated
classes, usage of internal memory pools, etc.
I'm not sure this is what you requested - do you need to tune the VM
for best performance or collect additional info during run or smth
else?
Actually I'm just interested in wall clock time for the purpose of
direct performance comparisons, but I always have a use for performance
statistics from JVMs. Some of the numbers you list are tricky to get
from my measurement infrastructure :)
thanks!

Hmmm ...
$ $DRLVM_HOME/jre/bin/java -Xbootclasspath/p:antlr.jar -XcleanupOnExit
-Xstats -jar $HOME/dacapo-2006-10.jar antlr
Unknown option -Xstats
Use java -help to get help on command line options
