I should also point out that 0.13ms per object is an
absolute best possible case for the database access.
This is reading straight out of Oracle's cache on a
local machine, with no concurrent threads. In a real
system, the database access would be MUCH slower than
that!

Now it only takes 0.3 seconds to load that object! Thank you so much!

I am not sure it can help for you, but sometimes I use this for "readonly"

transform tables like "TBL_CITY" or "TBL_COUNTRY" to "properties" file and
store this data on client side.

All the foreign tables should be cached indefinately. There are only a
couple rows in each.
Is a way for hibernate to, when loading PanelDemographics, the sql generated
would just select the id's of the foreign tables, then grab the objects from
the cache.
Absolutely. Enable JCS on the associated
Using Hibernate 2.0.3
We have a table "panel_demographics" (xml at bottom) which holds foreign
keys to many other tables. These other (metadata) tables all look basically
the same, at the bottom "Education" is an example.
A query like: PanelDemographics panelDemographics = (PanelDemographics)

Please find the src for the latest version of the Hibernate plugin. This is

The following is what has been included:

Thanks Christian,
That's a great assest to our tool chest!
Can you tell me how it affects Hibernate's caching?
Or is there somewhere I can read how it might, without searching the
sourcecode?
Thanks again,

Hi All,
I've just started workign with Hibernate and have run into something
which looks like it used to have a (partial) solution to at:

Which shows the following :

Hi,
I once suspect that hibernate take too much time in
doing dirty check during session flush. However Gavin
king and other hibernate-user disagreed with me.
I did a simple performance testing to verify the dirty
check performance.
My conslusion is that the performance is not so good
