[Kst] Interesting performance results

[George Staikos]

I just ran the performance test (QTimer) on my dual athlon machine with NVidia 
GeForce4Ti video card.  The most that plot update takes with three plots in 
one window (one is a histogram, one is a PSD, one is a vcurve, all streamed 
from a realtime ASCII file) is 10ms.  Label drawing is the predominant factor 
too!!  Here are some results for you to verify :-)
