Hi, Rob
I've been doing some testing with ActiveMQ 5.1, making it receive messages as fast as possible. What I noticed was a steady slow down as the messages kept coming to AMQ. I have to mention here that I intentionally didn't consume messages from the queue (so it kept growing) to see the storage capacity of AMQ. Below are partial results of sending messages over 100MB network using OpenWire to AMQ 5.1 running on FreeBSD. The trend of performance decrease suggests a possible bottleneck in the persistence module (which was Kaha by default). Obviously, I cannot assert this for sure. Even though Kaha is supposed to be the fastest storage mechanism supplied with AMQ, are there any configuration options to fine-tune it for heavy loads? This is a part of the more broad issue "how to make AMQ accept more messages per unit of time, thus reduce number of nodes in a cluster". 1000 msgs for 1516 msec. 659.0 msgs p/sec 2000 msgs for 2579 msec. 775.0 msgs p/sec 3000 msgs for 3657 msec. 820.0 msgs p/sec 4000 msgs for 4735 msec. 844.0 msgs p/sec 5000 msgs for 5875 msec. 851.0 msgs p/sec 6000 msgs for 8032 msec. 747.0 msgs p/sec 7000 msgs for 9110 msec. 768.0 msgs p/sec 8000 msgs for 10204 msec. 784.0 msgs p/sec 9000 msgs for 11360 msec. 792.0 msgs p/sec 10000 msgs for 12454 msec. 802.0 msgs p/sec 11000 msgs for 13579 msec. 810.0 msgs p/sec 12000 msgs for 14688 msec. 816.0 msgs p/sec 13000 msgs for 15875 msec. 818.0 msgs p/sec 14000 msgs for 17282 msec. 810.0 msgs p/sec 15000 msgs for 18500 msec. 810.0 msgs p/sec 16000 msgs for 19735 msec. 810.0 msgs p/sec 17000 msgs for 20922 msec. 812.0 msgs p/sec 18000 msgs for 22172 msec. 811.0 msgs p/sec 19000 msgs for 23391 msec. 812.0 msgs p/sec 20000 msgs for 24750 msec. 808.0 msgs p/sec 21000 msgs for 25954 msec. 809.0 msgs p/sec 22000 msgs for 28125 msec. 782.0 msgs p/sec 23000 msgs for 29282 msec. 785.0 msgs p/sec 24000 msgs for 30750 msec. 780.0 msgs p/sec 25000 msgs for 31969 msec. 782.0 msgs p/sec 26000 msgs for 33172 msec. 783.0 msgs p/sec 27000 msgs for 34454 msec. 783.0 msgs p/sec 28000 msgs for 35875 msec. 780.0 msgs p/sec 29000 msgs for 37235 msec. 778.0 msgs p/sec 30000 msgs for 39875 msec. 752.0 msgs p/sec 31000 msgs for 41250 msec. 751.0 msgs p/sec 32000 msgs for 42547 msec. 752.0 msgs p/sec 33000 msgs for 43813 msec. 753.0 msgs p/sec 34000 msgs for 45297 msec. 750.0 msgs p/sec 35000 msgs for 46610 msec. 750.0 msgs p/sec 36000 msgs for 48329 msec. 744.0 msgs p/sec 37000 msgs for 49672 msec. 744.0 msgs p/sec 38000 msgs for 51000 msec. 745.0 msgs p/sec 39000 msgs for 52688 msec. 740.0 msgs p/sec 40000 msgs for 54422 msec. 734.0 msgs p/sec 41000 msgs for 56047 msec. 731.0 msgs p/sec 42000 msgs for 57391 msec. 731.0 msgs p/sec 43000 msgs for 60719 msec. 708.0 msgs p/sec 44000 msgs for 61907 msec. 710.0 msgs p/sec 45000 msgs for 63422 msec. 709.0 msgs p/sec 46000 msgs for 64766 msec. 710.0 msgs p/sec 47000 msgs for 66360 msec. 708.0 msgs p/sec 48000 msgs for 67813 msec. 707.0 msgs p/sec 49000 msgs for 71563 msec. 684.0 msgs p/sec 50000 msgs for 72750 msec. 687.0 msgs p/sec 51000 msgs for 74204 msec. 687.0 msgs p/sec 52000 msgs for 75704 msec. 686.0 msgs p/sec 53000 msgs for 77266 msec. 685.0 msgs p/sec 54000 msgs for 78563 msec. 687.0 msgs p/sec 55000 msgs for 80125 msec. 686.0 msgs p/sec 56000 msgs for 82016 msec. 682.0 msgs p/sec 57000 msgs for 83500 msec. 682.0 msgs p/sec 58000 msgs for 85047 msec. 681.0 msgs p/sec 59000 msgs for 86516 msec. 681.0 msgs p/sec 60000 msgs for 90422 msec. 663.0 msgs p/sec 61000 msgs for 91641 msec. 665.0 msgs p/sec 62000 msgs for 93032 msec. 666.0 msgs p/sec 63000 msgs for 94579 msec. 666.0 msgs p/sec 64000 msgs for 95782 msec. 668.0 msgs p/sec rajdavies wrote: > > > So long story short - use the default message store (AMQ) in version 5! > > -- View this message in context: http://www.nabble.com/Poort-ActiveMQ-Persistence-Performance-tp12945570s2354p16797097.html Sent from the ActiveMQ - User mailing list archive at Nabble.com.
