impact of Nessus Scan on network

One of my customer's has asked what the network traffic level impact a
Nessus scan would have on a network given:
1. targets are all Windows
2. scan would be done with domain authentication.
3. approx 200+ servers scattered over 40 locations in the US spanning
east to west coast.
4. WAN uses MPLS cloud
5. Default configuration used: max number of hosts 20 max number of
security checks 4, check read timeout 5 seconds, plugin timeout 120,
number of packets per second port scan 500

Does anyone have a SWAG for how much traffic throughput per second a
Nessus scan can generate?

I'm mostly concerned about avoiding flooding switches in key points. Any
comments would be helpful. I've searched the Tenable blog and haven't
found any info. I counseled my customer that there are too many moving
parts to definitively come up with a figure. I was hoping others on this
list could share their experience on this point.

Thanks

Jim
