There may be a significant difference. For good performance pages should
be allocated with their physical addresses choosen such that maximum
cache hit rates can be achived. That's something which the current
buddy system for the free pages doesn't support. For RISC/os and IRIX
the performance difference accounts for 5 - 10%.
