I believe you should not worry too much. The biggest performance drop
seems to be heap-based ByteBuffers rather than off-heap ByteBuffers,
which is what you use. The only problem you'll see is that they don't
get vectorized, which you can probably live with. On the other hand,
heap ByteBuffers are very badly affected.
Sorry to cause a panic; I should have explained better.
Andrew.
