Thread 17 down below, as well as thread 37 immediately below, both show
startHandshake() in the stack, but only thread 37 has the calling application
in the same thread. I don't see anything in the startHandshake() method that
spawns off a thread, and it looks like return from this method is onl
Sorry - JMeter or custom Java code are only examples. Other contributions
will be considered as well.

This is a great effort here.
Please consider sharing test tools. JMeter profiles or custom java code.
One thing I'm considering is capturing performance tests in another repo for
ActiveMQ, together with baselines (i.e. captured runs - preferably with a
solid capture of hardware configuration det

the question is how many consumers, producers actively send, receive data on

standard IO means one thread serves a connection, independent of the actual

NIO means decoupling - a thread is allocated (from
Kevin, Sam was actually part of that original thread.
Sam, as you probably remember from that discussion, Christian pointed out
that NIO uses a thread pool so you'll probably only see a decrease in
thread usage if you have more consumers (and more producers) than threads
in the thread pool, and I
Wildcards can only match an entire name within a path. So *.*.*.out would
match A.B.C.out, but there's no way to write a wildcard to match A.B.Cout
in your example.
Also, > can only be used at the end of a pattern.

some work has been done in this area.
there are connection limits (on a transport connector) and message
size limits on openwire.
there are currently no destination or producer/consumer number limits.
Flow control helps but in a very dynamic environment it is difficult
to get appropriate limits t
Are you thinking about something like the producer flow control [1]?

Hi,
I was thinking about ways in which I cause DOS attack on activemq and how to
prevent it.
I can bring the setup down by:
1. creating large number of connections - restrict based on connectionID?
2. large number of destinations
3. large number of subscriptions, consumers, producers, wildcard

I read http://activemq.apache.org/wildcards.html but am still puzzled about
how to write a pattern that matches queue names with a particular suffix.
For example, for queue names such as A.B.Cout and D.E.Fout will
Thanks for taking interest in this Kevin.
As I already mentioned, I did those tests with 1 consumer, 1 producer and 1
consumer, 20 producers.
How many consumers and producers do you suggest I repeat the tests with?
Thanks,
Sam
