Benchmarking a java agent

[George Campbell]

I'm trying to see how much overhead a java agent is adding to the execution of an example program.  I see that there is @VmOptions annotation but it looks like it is applied to all experiments.  Any suggestions on how I can do this?

You can set options for a particular vm in your ~/.caliper/config.properties file and then select that vm with the --vm flag.  For example:

vm.jdk-special.home=/path/to/vm/home/dir
vm.jdk-special.args=-myspecialflag

That would still be two runs of caliper.  Is there a way have it work like a parameter? Or merge the results of two different executions?

[Gregory Kick]

You can specify as many vms as you'd like in a given run.  --vm=with-agent,without-agent will work.
