hello, i am trying to test the performance of geronimo under load for message driven beans. the observed behaviour is that i get a maximum of about 85 transactions per second. after this, tested with about 60 concurrent users, the performance drops again to about 45 tps. i hoped to increase the performance somehow.. things i already tried:
-increase the mdb pool size -increase the thread pool size -increase the connector-thread-pool-size unfortunately nothing helped, the performance situation remains the same. another observed behaviour is that in the time of silence between tests the server needs some time to fulfill the requests sent before. so i see it is still working although i am not sending mdb-requests anymore. i suppose these are the requests that are still in the queue and have to be finished. i think this is the reason for the performance drop with more concurrent users. i would like to see it perform without this "aftertime-working" and handle the requests "in time". maybe someone can give me a hint which other values could be important to change for the performance of mdbs getting real good. i thank you very much for your help, greetings, mario -- View this message in context: http://www.nabble.com/MDB-performance-tuning%2C-configuration-tp16234678s134p16234678.html Sent from the Apache Geronimo - Users mailing list archive at Nabble.com.
