Does that imply entries are kept memory resident or just that there is a

There are lot of caches involved in ADS, in many places. Some of those
caches can be controlled, for instance for the number of entries in
memory, the same for the index (cacheSize parameters in the server.xml
file).
However, if you have a limited amount of memory, as this is relying on
Java, you have no way to control precisely the memory consumption and
limit it to a specific amount. Although, the less memory you have, the
less entries you'll have in cache, and teh worst will be your
performance. You can have a 100x decrease in perf if you hit the disk
each time you have to grab an entry. You have to be aware of that.
What's exactly is your memory limitation ?
