No I didn't however, I'm just in the process of setting up something similar using Broker 8.0.0.2. I shall have to see if there are any delays there.

Every time you reinvent the wheel the more square it gets (anon). If in doubt think and investigate before you ask silly questions.

We deployed it to WMB 8 Hypervisor version (RHEL 6.2) and it worked perfectly . Must be something with the configuration/tuning and we're trying to figure it out . Thanks everyone a lot

We found that in Linux system (not hypervisor edition), if we deploy message Flow using the user who installed message broker, the problem just gone.

However, in Windows environment, deploying the flow using user who install the software does not fix the issue.

Nothing about the user that is performing the deploy of the exact same bar file should alter how the bar file performs.

Possibly the issue is related to the Nagle algorithm (TCP_NODELAY etc..) ? Although I thought that was just related to sending packets and not receiving them!

Possibly the issue is related to the TCP configuration of the relevant systems.

Possibly the issue is related to the relative TCP performance between the sending system and the various different broker receiving systems.

Possibly the issue is related to an internal defect in WMB.

Possibly the only way to resolve all of these possibilities is to apply troubleshooting, and generate data from which to create hypotheses or open PMRs.
