We have a Sun Fire T2000 Server with a total of 16 1GHz CPUs running Solaris
10.
We have built Plone using the Universal Installer to run ZEO:
./install.sh zeo
Plone works, but unfortunately runs very slowly compared to a test
installation on a solaris desktop (the T2000 is three times slower).
Tests have indicated that at any time python is only using ~6.3% of the CPU
available to the system:

This equates to 16th of the total processing power, or one CPU being used.
Is there any way to configure plone/python to scale to the full number of
CPUs in our installation?
Cheers, Jim
