Support for M6in #23

Closed jacob-aegis closed 1 year ago

jacob-aegis commented 1 year ago

m6in.32xlarge can support up to 200 Gbps. My application only needs the NAT for inbound traffic. That being the case, is it feasible to use fck-nat with a m6in.32xlarge and get 200 Gbps inbound? I can see you've noted 5 Gbps for egress, but I don't see a limit for ingress.

From the docs:

To other Regions, an internet gateway, Direct Connect, or local gateways (LGW) – Traffic can utilize up to 50% of the network bandwidth available to a current generation instance with a minimum of 32 vCPUs. Bandwidth for a current generation instance with less than 32 vCPUs is limited to 5 Gbps.

So it would be "up to 50%" of 200Gbps, so a max of 100Gbps. AWS doesn't provide any further guarantees.

Thanks for the quick response. Current need is nowhere near 200 Gbps, but good to know that the real theoretical limit is up to 100 Gbps.
