How scaleable is MySQL 5's Innodb with multi-core CPU's?

[mos <mos99@xxxxxxxxxxx>]

Is there a problem with InnoDb scaling with multi-processor CPU's? 
Apparently after reading the Tweakers.net article,  with only 40 
simultaneous users the performance of MySQL 5  will collapse.

Has this been fixed? Or is there a work around?
I need to write a high capacity web site that will have hundreds of 
queries/second (25% of them transactional), and I need to know if InnoDb is 
up to the job.

Is Falcon going to be any better than InnoDb? Any release date?

TIA
Mike
