5 times a second is not much - allocation take only a few microseconds on a
typical modern PC. That said, you'll get the best performance by making a
single large-enough allocation and re-using it time and again. You'll also
avoid fragmenting the GC heap and causing excess collection cycles by
holding onto a single large memory allocations.
