In modern Zope versions you can use Zope 3 views.
The corresponding templates are trusted.
For earlier Zope versions, there is "TrustedExecutables" (they do not
yet work for Zope 2.10).

I doubt that the large number of objects is the real reason.
The large number of objects result from full text indexing:
the object is inserted into the document list for each word it
contains. However, full text indexing is slow and expensive - independent
from the insertion into the document lists.
Obtain a profile and check whether this is really true....

DTML is likely to be faster: it has a C implementation and is
simpler than ZPT. I expect a factor of about 4.
However, very often the total time is not dominated by the
rendering itself but e.g. determining the values that should be rendered.
