ActiveMQ routes performance
Sorry in advance if I should have posted that in ActiveMQ list, but here is
our case.
We are running the same test with two different setups:
Setup 1:
------------
We are using a single ActiveMQ broker and a single Camel with the routes:
from( "jetty://http://..." ).inOnly( "activemq:queue:queue2" )
from("activemq:queue:queue2?maxConcurrentConsumers=100").bean( myProcessor,
"delay" )
The activeMQ component uses
a org.springframework.jms.connection.CachingConnectionFactory
myProcess.delay() delays for 200 ms
Setup 2:
------------
We are using two ActiveMQ brokers and a single Camel with the routes:
from( "jetty://http://..." ).inOnly( "activemq1:queue:queue1" )
from(
"activemq1:queue:queue1?maxConcurrentConsumers=100").inOnly(
"activemq2:queue:queue2"
)
from("activemq2:queue:queue2?maxConcurrentConsumers=100").bean(
myProcessor, "delay" )
Both activeMQ components use their
own org.springframework.jms.connection.CachingConnectionFactory
------------------------
All ActiveMQ brokers are identical, with:
- kahadb
- <policyEntry queue=">" queuePrefetch="20" producerFlowControl="false"
optimizedDispatch="true" useCache="true">
- <memoryUsage limit="4 gb"/>
- <transportConnector name="openwire" uri="tcp://0.0.0.0:xxxx"/>
We test the setup by sending http requests from jmeter with 40 threads and
1200 tps filter. We monitor the enqueue and dequeue rates of all the
queues, and notice that:
Setup 1:
------------
queue2 enqueue: ~900 tps
queue2 dequeue: ~50 tps
Setup 2:
------------
queue1 enqueue: ~1200 tps
queue1 dequeue: ~1200 tps
queue2 enqueue: ~1200 tps
queue2 dequeue: ~150 tps
This means that the 2nd setup causes the brokers to behave much better and
gives us a much higher throughput for our processor.
How can this be explained? Is there any configuration that will let us
achieve the same performance with a single broker?
Thank you
Xenofon

Well apparently something is alleviated, but I'm trying to understand
what... The 2 queues are sequential, and the 1st queue is almost always
empty, so I cannot see why I have a bigger buffer.

With the intermediate queue you have a bigger buffer, a 2nd queue.
There might be a bottleneck on certain calls from your initial
endpoint which having the 2nd queue alleviates.

Thanks for the tips. I'm trying, however, to understand why there is better
behavior with the intermediate queue, given that all other parameters
(threads etc) remain the same.
Also this is a test; in production we normally use about 800 concurrent
consumers, and the resource use in the servers is pretty low.

Re: ActiveMQ routes performance
Posted by Ben O'Day <be...@initekconsulting.com>.
tough to say given the unknowns about your setup, but here are a couple of
things to consider...
-for kahadb, set enableJournalDiskSyncs to false to get much better
throughput
-try fewer consumer threads...100 is a lot and you generally have
diminished/negative results with larger thread counts
-tune your CachingConnectionFactory (notably the sessionCacheSize should be
increased from the default)...that said, beware of using this with polling
consumers connections (see
http://stackoverflow.com/questions/5916638/autoreconnect-problem-with-activemq-and-cachingconnectionfactory
)
-alternatively, try using the AMQ PooledConnectionFactory and see if you
get better performance
