Software/Hardware needed to trade after the FOMC

Which is why you shouldn't use a general purpose updater. Write one specifically tuned to your needs. Takes longer, but performance is better.

Rather you than me. Recall that TWS is cross platform. Windows, Unix/X11 and Mac at least. With Java than means using Swing for a truly portable GUI (rather than SWT). Much better to optimize components and procedures used in Swing than re-invent the wheel.

I can't really see how IB had much choice other than to do it using standard Swing components, which is not to say that it may not be possible to improve performance by optimizing some of the code.

Well, IB is in luck that more and more traders have very fast systems (> 3 Ghz CPU's).
I just measured that only the drawing of a 50 ticker-row sheet, costs about 500 Mhz of CPU...just imagine so much power only to draw the ticker-cells of 50 rows of fast updating cells.
{optimized code uses 50 Mhz, which is actually a lot as well}.

I have not measured the Charts but they are clearly not fast either.

Sure: Java has its advances of crossplatform use, but we are talking here about fast-real-time trading applications!..The faster the better.....
I will stay with my C++ apps for sure.
