Hi Reza,
that's correct - it's a trade-off between performance and reliability
- so in ActiveMQ 4.0 we opted for safety first.
cheers,
Rob

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

Dear Rob, The current snapshot performs better than RC2 but still
it is too slower than 3.2.2 . With a benchmark in the same
environment I got the following times:
3.2.2 ----> 8 sec.
SNAPSHOT ----> 43 sec.
RC2 --- > 77 sec.
So you see the diffrence is a lot(8 vs 43).
Thanks,
Reza

Dear James, I also tested with RC2 but it is still slow. We are
interested of the features you provided in version 4.0 but we
don't want to loose performance. I hope you would reach to the
performance of 3.2.2 in next releases of 4.0 .
Cheers,
Reza

4.0 are you testing? FWIW we've only recently started
tuning 4.x heavily, certainly SVN HEAD is looking quite good.

Hello,
I used a simple benchmark to compare the performance of 3.2.2 vs
4.0 . I
suprised why 3.2.2 performs very better than 4.0, I thought I
could be wrong
or maybe my configuration has a problem but I couldn't find
anything bad in
configurations(I used default and without persistency). I have
attached
codes that I used. Please let me know why 3.2.2 performs better
than 4.0.
The benchmark works with a queue asynchronously.
Run the consumer to register consumers and them run the producer.
Best Regards,
Reza
