@swifty - Yes we have agreements with upstream and manage our connections there with throttling so that we don't exceed our allotted connections is a given time period.

@thomas Thanks for those metrics.  We are looking to see if the connections per second is generated with our current devices.  What we do know is that our max outbound connections will get as high as 16000 for a period of time (maybe 2-4 hours) and will occasionally burst up to around 20000.

How does that compare to the metrics that you mentioned earlier?

Thanks,
John
