Would you care to post some _exact_ data that disproves 120ns?  Did you see
Matt's number in the post parallel to yours?  Using current DDR ram speeds?

So your "no amount of convincing" leaves me cold.  "no amount of data" has yet
been presented to show any machine with < 100ns latency.  Feel free to disprove
it but post your code.  Any old sloppy C code won't do, the code has to be
written to test latency, not prefetching or cache reuse.
