You just doubled the number of resources (mrs+page_vectors) allocated
for a performance optimization (25% in large writes). I'm asking myself
if that is that acceptable? We tend to allocate a lot of those (not to
mention the target side).

We're using same amount of mkey's as before (sig + data + meta mkeys vs. sig + internal_klm + internal_mtt mkey).

But each mkey has twice of mtt/klm space..

No. It's the same size (I reduced the HCA cap, remember ?)

I see...

So we can drop this...
