"50 million cycles" is a meaningless measure far detached from the actual work being done. You're choice of front end framework has almost nothing to do with total CPU use: how the text box looks (rounded corners, drop shadow) has far more impact on cycles overall. But it doesn't matter. Cycles are not in shortage. CPUs are mostly idle. If something takes less than 16ms to complete, you simply won't notice.
