Anyone knows how fast memory can be allocated on a quadcore 2 GHz Intel system?

I'm asking to estimate how many virtual address bits would be sufficient to guarantee that no pointer is ever reused before the underlying hardware dies anyway.

@ptesarik 1GB/sec should be reasonable estimate.

@pavel Thank you! That's 30 bits. If I estimate maximum system uptime as 5 years (0x9660180 seconds), that's another 28 bits, which means that 58 bits should be in fact enough, and a full 64-bit virtual address space should have quite some reserve.

Hmmmm.
