<List of features snipped>

Can someone who has a deeper understanding of this area than
I please contrast (ideally against the mxODBC Zope DA feature list)
things with ZOracleDA/DCOracle2?

The links from <http://www.egenix.com/> took me eventually to
and the "Oracle ODBC Performance - Faster than Native" stuff.

there. Might mxODBC Zope DA offer advantages to Zope/Oracle sites?

We've had a tortured history with Zope+Oracle+Solaris (cf.
<http://www.zope.org/Members/glpb/solaris>) and are about to
side-step this by going Zope+Oracle+Linux.

But the Oracle bit (i.e. ZOracleDA/DCOracle2) of the equation still
looks dubious from time to time and so hence my questions.
