Re: [xmlblaster] Published messages are delayed.

I'm developing an application that publishes a lot of messages

Fast, but not that fast (< then the 672 messages per second performance
value mentioned on the website)
The problem is that the messages are delayed towards the subscribed
Sometimes it takes a number of seconds before the messages arrive at the
subscribed clients (even with 1 subscribed client) and
when they finally arrive, it is like they are updated in bulk.
The consequence is that there are more than 1000 entries in the callback
queues (queue overflow).
Increasing the callback queues is not a solution because there is still
a large delay before the subscribed clients
receive the messages.
When I decrease the speed of publishing messages, eg. putting a delay
(eg 100ms) in the code in between 2 message
publications, the message arrive almost immediately at the subscribed
Does anyone know what can be problem causing this delay.
could you please provide more details?
Which OS and version and thread lib, which xmlBlaster version, which Java version,
persistent or transient messages, the size of each message etc.
