Plone is ZPT centered and ZCatalog queries centered. It is a lot of=20
object sitting in a memory cache and a lot of processing power is being=20
consumed. Thus processor cache is not sufficient for the task and speed=20
of conventional memory is becoming important. This is why I am asking=20
about memory subsystem configuration.

I am not sure about dual-processor system. Both processors will be=20
competing the memory, the bus unless there are separate channels. If=20
anybody now details about CMF/Plone and how they cope with different=20
memory subsystems it would be great.

There is psyco which can speed things a lot but with P IV we have=20
experience that it gives _nothing_ at all. I am sure it is there and it=20
is active but I cannot see any benefit from compiled code. If somebody=20
has benchmarks for python/python+psyco on different hardware it would be=20
great.
