Why this happen? I think that the jackrabbit make cache...or not?
jackrabbit contains several caches, that's correct. but none of them caches the
result of a query.
e.g. jackrabbits query manager contains a cache that speeds up hierarchy
resolution. the jackrabbit core contains cache for items. and finally even the
filesystem of your OS will have caches.
there is no way you can disable them all. that's why performance tests are
usually done with a 'warmed' up system and well distributed / randomized test
values.
