EC2 m5n.2xlarge limited bandwidth?

0

When a user is uploading a file to my m5n.2xlarge, the server become quite slow (network). The user is uploading at 100Mbps, I am not sure why the server is not able to handle this bandwidth. From the specs:

  • Network: Up to 25 Gbps
  • EBS: Up to 4,750 Mbsp

I am limited because of EBS, or credit balance (I don't understand this notion of credit balance)? Should I use another instance? Thank you in advance!

Did you validate the ENA drive is enabled on the instance? https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/enhanced-networking-ena.html

You can also leverage CloudWatch metrics to see the NetworkIn to the instance to see how much throughput is being used. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/monitoring-network-performance-ena.html

  • ENA enabled yes. I configured alarms, is that boolean: ethtool_bw_in_allowance_exceeded > 0 for 1 datapoints within 5 minutes (did the same for the 5 of them). Does it makes sense?

Network performance from a client to a server depends on a lot of things including the network in between. Could it be an issue on the server? Sure. But I would first look at the path between the client and server. Run tests on different clients connected to different networks and isolate where the performance issue is coming from.
