I have detected aprox. 5% performance regression in Camel scatter-gather EIP pattern test in Fuse 6.3 R11 #376. Test application can be found here.

I suspect multicast causing this regression as performance drop is also visible in other example using multicast with aggregation strategy here

Performance test results are here

Performance results are average throughput of http request-response per time frame on client-server architecture. Tests were executed on jdk1.8.0_191.
