My question for you is why are you calling it several hundred times a
second? Is it because you are calling the function on a number of different
objects several times a second or that often on one object due to
application of mouse or other input to provide incremental transforms? If
the latter is the case, you may want to apply incremental transforms to an
intermediate matrix and then update the model transforms only once or twice
a frame (60 to 120 times a second or less depending on your actual frame
rate). This will be much more efficient and will reduce the amount of
"garbage" being generated.
