To understand performance, you need to analyse timings through each part of the chain, what is the maximum capacity, and where are the bottlenecks located. DP and MQ are unlikely to be limitations. The app logic and system resources like network capacity, memory, cpu and disk i/o capacity need to be examined.

I asked this yesterday about IIB and transformation. The DP chimed in quickly, 'Transformations on the wire'. Always wonder what that meant. I mean you have to read it in, transform in memory (supposedly it is 4 meg xst) and then push it out.
But there are several, maybe 3-4, back and forth interactions from IIB to DP. There has to be some incurred latency. I do not have a rock solid understanding yet, but the flow diagram made my head spin. |
My first instinct would be to remove the back and forth between IIB and DP.
There should be one call only from DP to IIB and back.
Anything else should really happen from IIB to IIB. Number 2 is if you're having multiple calls I'd expect each one to use TLS. This would considerably slow down the interaction with encrypting and decrypting at each end.
Maybe time to revise the design? On top of it i'd expect XSLT to be faster on DP than on IIB (think all about this transformation on the wire happening in DP...)

It's marketing terminology for a black box, being likened to a switch, router or other network device, but much smarter.
