Centos – Moodle on EFS is slow

amazon-web-servicescentosmoodle;

I hope you can help me with me problem with EFS.

I have installed Moodle on an Amazon EC2 and I mounted EFS following the guides provided in the website.

The problem I face is that Moodle is very slow when using EFS.

I did the following tests:

  1. EFS + RDS = slow
  2. EFS + local MySQL = slow
  3. Local Filesystem + RDS = perferct perfomance
  4. Local Filesystem + Local MySQL= perferct perfomance

EFS performance is set to Max I/O and I have read the additional considerations here:
http://docs.aws.amazon.com/efs/latest/ug/mounting-fs-mount-cmd-general.html

Is there anything else that I miss?

Could you please give me some ideas, on what might be the problem?

Thank you for your time to read this post

I have the same problem. One solution is to create a virtual server with network performance and SSD disks and makeit the NFS for the EC2 instances. Sounds insane, but EFS doesn´t work.

If you get the things done in AWS/EFS, please let me know how.
