[xmlblaster] Scalability and Performance question

[David R Robison <drrobison at openroadsconsulting.com>]

We are currently deploying a statewide xmlBlaster network for regional 
data integration and sharing. The data being shared is standards based 
XML messages wrapped in an EDXL-DE message. We currently have deployed 6 
xmlBlaster nodes, most operating as both domain masters and slaves. We 
foresee the network growing to about a dozen nodes with 2 dozen domains 
mapped onto the cluster of nodes with up to 1500 simultaneous users 
attached to the various nodes. Our client has expressed some question as 
to the ability of xmlBaster to scale to multiple nodes and multiple data 
sources. I am curious as to what other experience others have had in 
deploying "large" xmlBlaster networks and what performance is being 
realized by xmlBlaster.

Thanks in advance, David Robison
