I can't comment on CMF or Plone becuase I don't use them I have a python product I wrote that we use and it works quite nicely on this system.
Plone is ZPT centered and ZCatalog queries centered. It is a lot of object sitting in a memory cache and a lot of processing power is being consumed. Thus processor cache is not sufficient for the task and speed of conventional memory is becoming important. This is why I am asking about memory subsystem configuration. I am not sure about dual-processor system. Both processors will be competing the memory, the bus unless there are separate channels. If anybody now details about CMF/Plone and how they cope with different memory subsystems it would be great. There is psyco which can speed things a lot but with P IV we have experience that it gives _nothing_ at all. I am sure it is there and it is active but I cannot see any benefit from compiled code. If somebody has benchmarks for python/python+psyco on different hardware it would be great. m. -- Myroslav Opyr zope.net.ua <http://zope.net.ua/> ° Ukrainian Zope Hosting e-mail: myroslav@zope.net.ua <mailto:myroslav@zope.net.ua>
