I would assume that this feature is working since it comes
from the Haufe Zope fork

Hmm, oh well, my bad...
In that case it must just be that their pickled form is huge compared to
an int ;-)
Sure:

How come? Unpickling doesn't call

Hanno Schlichting recently posted a nice graph showing the persistent
structure of a Plone Page object and it's 9 (!) sub-objects.

That graph isn't quite correct ;-)

Hi.
I have a configuration with one ZEO database server (ZODB 3.8.1) and two
physical servers housing four single-threaded ZEO clients each. There's
some 15gb of blob data in the (Plone) site.
Setting up and maintaining NFS to share direct access to the blob data
is beyond what I can support in

Am I correct to assume that sharing the blob-cache between the four

have any mechanism to synchronize read/write activity to the blob-

I've just released the first beta of ZODB 3.9.
Awesome :)
I thought there were some outstanding issues with the cache-size-bytes
functionality. Got all of these resolved / reviewed by now?
Thanks,

Cool :)

We are running both Plone 3.0 and 3.1 in production with ZODB 3.8.1 on
two quite large sites (one has RelStorage, the other one blob storage).
I'd consider it

I can say that the combination of 3.8.1b8 and Dieter's

Besides the RelStorage site where we were running into problems as
mentioned in the other thread, we also use the ZODB 3.8 branch (beta8
plus the first two beta fixes) in a smaller site with blob storage for
