Online Docs : Performance
First, it's important to know exactly what Fluid is.
Fluid is a realtime fluid dynamics modeler
and renderer. What does this mean? Well, it means that for each frame
of animation on the screen the program has computed the reaction and
involvement of a "fluid" medium and has then taken that numerical
model and produced an image from it using rendering techniques that
are commonly used in scientific visualization. Fluid does all of this
for each frame of animation. Therefore, if you are getting around 50
frames per second (about right for a dual-proc 867 G4 using a resolution
64 grid...more about this later) then Fluid is recomputing the movement
of the liquid and rendering it 50 times each second. This is an incredibly
complex task—a task that could have only been accomplished on
supercomputers merely five or six years ago.
