I noticed that when processing large data (which may require 1Gb memory for the application while it is running) the application may finish its processing approx after 10 seconds. the cleanup part (which consists only of calling the pool release methods on allocated objects) on the other hand, takes many minutes (I usually give up after 5 minutes) debugging the code i noticed that the while loop in the nextof function (of SIMPLE SEGREGATED STORAGE.HPP) takes many iterations. this leads me to the belief that the reason the cleanup takes too long is because trying to cleanup 1GB memory of million of objects at once causes pool to retain all its chunks in the hope of more allocations in the future which in turns causes it to waste all computation on running to the end of (endless) lists in the nextof function I will appreciate a suggestion on how to fix this until a more permanent solution is applied to the pool library thanks aviad aviadr@pob.huji.ac.il ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=107586&aid=995270&group_id=7586 ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
