database size | shared CentOS | t2.micro EC2 CoreOS
2.4 Go | 1.5 sec 160% CPU | 30 sec 3% CPU ??!!
254 Mo | 0.35 sec 35% CPU | 0.21 sec 30% CPU
224 Ko | 0.24 sec 2% CPU | 0.14 sec 3% CPU
The CPU usage on the t2.micro is not what it should be for the 2.4Go database and explain the extreme slowness of the request. But why ??
