Database instance slow after spawning it using an AMI (for mongo)?
Reason: https://forums.aws.amazon.com/thread.jspa?threadID=223779
- If disks are not too big just do this on each mounted disk:
dd if=/dev/xvda of=/dev/null bs=1M
- If big dataset needed for database use Amazon EBS fast snapshot restore for big disks. Then spawn the instance using AMI with FSR support in your region.
