1) create objects
2) get Objects
3) invoke methods on objects


I did some testing:

While cpu-consumption is very low (means the cpu does nothing), ANY
operation on objects stored in ozone takes a very long time:

1) create objects ~ 200 ms
2) get an object and invoke a method ~ 600 ms

I iterated over these steps several thousand times. The measured response
time is very constant (does not change much over time), so there must be
some basic problem while interacting with an ozone-db.

Is this sort of "RMI-overhead"? If so, this renders ozone useless ?! It
takes several seconds to build a complex object tree (which would take less
than 10 msec locally).


wondering,


Lars
