demo: Increase timer interval to 100 ms

Timer intervals shorter than about 100 ms are unnecessarily taxing
on system resources. Also, on systems like Windows the smallest
resolvable time unit without using high precision timers is about
15 ms. Regular timer intervals should be well above that value to
avoid being dominated by noise and round-off.
