How about this wording:

"Review Simon's claims to improve performance</pre></blockquote><br /> What sort of evidence is usually compelling? It
seemsto me that this sort of change only benefits configurations with dozens or more CPUs/cores?<br /><br /> I ask,
becauseI saw a few references to "I see no performance change - but then, I don't have the right hardware." It seems to
methat it should be obvious that contention will only show up under very high concurrency? :-)<br /><br /> Cheers,<br
