[opencms-dev] Reduce calls to DB

[Tom Wolf]

Hi Michael,
 
Thanks - I just found out about the commercial version for medium-large sites - I wonder what the price is...
 
I debugged the core, and it seems that permission checks aren't done via the DB - it looks like the flexCache only works on the actual file content, but the OC first needs to retrieve the object information .
 
Is there any open-source module for this?
 
Thanks
