I guess what I said is that most of the time latency is not as important as throughput. And in those scenarios it generally works fine.

The best out of both worlds though (although then it requires more manual work) is pre-allocating HugaPages in advance and then let application use them (if the application supports it) or through libhugetlbfs (if it doesn't).

Edit: changed hugetlbfs to libhugetlbfs, so it's easier to find how to do it with man libhugetlbfs
