Hi,

I used RAM cache a while a few months ago on a Zope (3.3.1) install
with a ZEO context and didn't notice any problem ; and as far as I
know, I don't see any link between them, as cached data is stored in
memory and not in the ZEO database.

Actually, I switched to memcached to be able to share cache data (as
well as sessions data) between several front-ends. This required just a
small interface and two adapters (one to work with a RAM cache and
another one to work with memcached).

No problem for me to share experience if you want to work on a
dedicated package.

Best regards,
Thierry

Thierry thanks for your response. Yes I meant that the cache is local to a node and not visible to the cluster
moving to central storage like memcached is what we are looking for.

Ok thank you. Maybe we can build a product that is released to the community.
