[Zope] Too many ZODB object loads...

[Suresh V]

On the database Activity tab in the Control Panel, I am seeing a high
number of Object Loads (400K per hour). My cache size if 60K from what I 
see in the Cache Parameters tab, each of the 4 threads is well within 
this limit. My database has about 1M objects.

The symptom is that Zope appears slow when adding/editing content.

Any idea if this is a problem?
