I'm building a similar infrastructure (different purpose). Can you give a few more details about the problems you ran into? What version of Go? Message rate per second? Message size? What was the % increase over average response time during GC? What class of hardware? I did notice the Go's GC improved between 1.0 and 1.1. Thanks!
