Hi Rob, Yes, You are right. I changed the property and now the benchmark performs quite fast with the snapshot version. But what would I loose if I set useAsyncSend = true? I think I get no exception if a message cannot be delivered, right? Cheers, Reza
Rob Davies <[EMAIL PROTECTED]> wrote: Hi Reza, this is good feedback - something that has changed between activemq 3.x and 4.0 is that by default messages sent from a MessageProducer now wait for a receipt from the message broker that the message has been received. So a property you could set on your Connection Factory is to set useAsyncSend = true. I'd be interested to know if this makes a difference for you. cheers, Rob On 23 Apr 2006, at 15:25, reza aliakbary wrote: > Dear Rob, The current snapshot performs better than RC2 but still > it is too slower than 3.2.2 .
