Thanks for quick response. The bridge is deployed at JBoss Messaging side

In our case, the messages (1000) are already available in the ActiveMQ queue. 
i.e for testing purpose, the messages are already posted to the queue and left 
their without consuming. When the bridge is started, it is actually waiting for 
 secs and consuming the messgaes - there is a delay here eventhough the 
messages are already available in the source queue.

hi,

where did you deploy the bridge? at the ActiveMQ side or the JBoss Messaging 
side?

If you are sending a lot of messages in a fairly constant stream it doesn't 
make a lot sense to me why you are setting maxBatchSize to a value other than 
-1, since the batch will be sent anyway when maxBatchSize is reached.

Regarding the speed of bridging, this is a function of many factors including:

The size of your messages
Are the messages persistent?
The bandwidth of your network
The round trip time of your network
The speed of the ActiveMQ server
The Quality of service mode you are using.
The speed of the JBM server

So it's very hard to quantify.

Thanks, we had already gone through JBM docs. 

What we noticed is that when MaxtBatchTime is set as 1 milli second, bridge is 
sending only one message. According to that in one second, bridge should send 
1000 messages which is not the case. What we would like to know is why the 
bridge is taking that much time to consume the messages. For 50 messages, 
bridge is taking almost 4 secs to consume. Our requirement is to process 650K+ 
messages over the WAN in 1 hour.

We tried with higher values for batchtime, but the through put was still low.

Hi, here is what JBM doc says


  | 9.3.11. MaxBatchSize
  | This attribute specifies the maximum number of messages to consume from the 
source destination before sending
  | them in a batch to the target destination. It's value must >= 1
  | 
  | 9.3.12. MaxBatchTime
  | This attribute specifies the maximum number of milliseconds to wait before 
sending a batch to target, even if the
  | number of messages consumed has not reached MaxBatchSize. It's value must 
can be -1 to represent 'wait forever',
  | or >=1 to specify an actual time.
  | 
  | 

Please note the unit of  MaxBatchTime value is milliseconds. I think give it 1 
is too small.
