Poor performance under load





------- Additional Comments From dirk.verbeeck@pandora.be  2003-08-13 12:59 -------
In my tests notifyAll() doesn't have a mayor impact.
Using notify() would require other changes as well.
(The thread that woke up should notify the next thread after getting its object)

I only removed the "synchronized" from the borrowObject method.
Performance now much better.
See also the results from the new
org.apache.commons.pool.performance.PerformanceTest

This test uses the SleepingObjectFactory (includes penalty for heavy operations)
makeObject      500ms
destroyObject   250ms
validateObject   30ms
activateObject   10ms
passivateObject  10ms
