t2.micro useless.loading of cpu is limited to 10%
I have a kali Linux car a t2.micro package. At execution of any problem of cpu=100 of %, but on the expiration of time several minutes of Amazon limits loading of cpu=10 of %. At the same time cpu Kali linux displays loading of cpu=99,9 of % the % ec2=9.8% console. Don't provide support on https://forums.kali.org (It is forbidden to obsuzhat Kali Linux Amazon at a forum).
Sounds like you used all your CPU credits allotted for a t2.micro instance. Once you do so, t2.micro's are limited to ~10% "baseline performance" see: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/burstable-credits-baseline-concepts.html
