Each of > them will: > > 1) insert it's own set of objects, > 2) lookup every successfully inserted object and finally > 3) remove objects in several rounds until all of them have been removed, > making sure the remaining ones are still found after each round. > > This should put a good amount of load onto the system and due to > synchronising thread startup via two semaphores also extensive > concurrent table access. > > The default number of ten threads returned within half a second on my > local VM with two cores. Running 200 threads took about four seconds.
