If JBT were running on a headless unix environment such as FreeBSD 8,
then how would TWS run?
Aren't TWS and JBT required to be on same box ?

12.7 times faster? On the same box?
My question: Is it possible to run live trading from shell script and
command prompt without java GUI
Yes, it's certainly possible, with some code modifications. However,
I'd note two things:
1. In the forward test and trade modes, JBT consumes very little
memory and CPU. You can run dozens of strategies simultaneously
without any degradation in performance. I doubt that you would see
much improvement by running without the GUI.
2. What's really slow is backtesting (because it needs to deal with
huge data files with millions of data points and keep the chart data
in memory) and optimization (because the optimizer permutates through
a large number of parameters). If your optimizer runs 12.7 times
faster on FreeBSD, there is certainly a value.
