I've just send my results ;)

Good or bad... it depends. It's much better than 
it was with Zope 2.8.0, it is better than with 
Zope 2.7.2 but it is not perfect because 
errors are still here.

Our application will have about 500 users or more.
Of course they won't be working simultaneously and 
app will be running on much faster machines than 
one used for tests but I suppose that some errors
will appear.

For me these results seems really good. 
Another good thing is that the SQLRelayDA is going 
to be more stable than DCOracle2 and is even faster 
than DCO2. I have almost ready products, scripts and
changes to SQLRelayDA that can convert application
from DCO2 to SQLRelay with one click and we are 
going to resign from DCO2, but still more testing 
is necessary.


Previously you've written that:

"Zope 2.8.0 ships with a "TemporaryStorage" 
implementation (used by sessions in the default
configuration) which does not implement MVCC.  
The one in 2.8.1 (now in beta) and better will
implement MVCC"

so I hope that maybe next 
Zope 2.8.x release will be using MVCC for OOBTree 
(if this is the point?). Does anybody know 
something about that?
