I was once told by a chap lucky enough personally own an Octane dual R14K 600
that the R12K fixed a number of issues in the R10K CPU. One of these was to do
with cache misses. If you're not seeing max performance out of the system with
an R10K processor, I would imagine this might be a considerable reason.
/me hopes this information doesn't further the resellers ability to keep the
price of 2nd hand R12K parts stupidly high....
