DCACHE_SIZE

hi,
at the moment we are trying to optimize VASP for an IBM power6 machine. This parameter -DCACHE_SIZE what is it actually for? And more important how can you find/calculate what value you should use(or start from as a good estimate)
A power6 machine ahe 64kb L1 cache, 4Mb L2 per core and 32Mb L3 per core...
thanks
