Hi Petteri,

Yikes thats slow. On debian/x86 the png is being generated instaneously. On
the monitoring screen of our app we are cycling through graph displays every
10 seconds plus allow users to step through them at their own pace. We could
have a network of 50 sensors, for instance, capturing data and the user
scrolling through graphs (one for each sensor).

Oh well I will build it and see what happens. :)

Thanks Petteri,
