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.
60 k is unusually large. Are you sure that this is not the combined size of all caches (such that each cache has a capacity of 15 k)? When the ZODB reported that it has read some number of objects, it is very likely that it did indeed.

Do you use text indexing? with ranking information? The usual cosine (OKAPI) ranking requires a large amount of data. When you perform modifications, usually the problem is not the amount of objects read but the amount and size of objects written. Use "fsdump" to determine the size of your transactions. -- Dieter
