Hi @mikemcquaid

We were hoping to keep the [tiered compilation flags](http://docs.oracle.com/javase/7/docs/technotes/guides/vm/performance-enhancements-7.html#tieredcompilation) because they make the JVM start up faster. They optimize the JVM to run as a client-side tool which needs quick startup time, as opposed to the default settings which are for long-running servers where startup time is less important. On my laptop, running "helios -h" executes about 15% faster when the flags are set.

Would it be ok to leave them in?

Thanks,
Ryan
