Hi all

We are using ArangoDB on the images published in AWS Marketplace. After our 
own few customisations via apt-get plus making a new AMI, instances 
launched from this has very bad write performance on /vol/data. Then after 
a stop+start the problem goes away. A little write test program writes a 
file of 280MB. It takes more than 50 seconds, and only 2 seconds on an 
instance that works like it is supposed to.

Also mentioned here:

How to reproduce the issue:
1) launch a fresh ArangoDB instance from AWS Marketplace (c4.xlarge).
2) run apt-get update and upgrade.
3) Make a new image and launch a new instance. You will see the problem.
4) Stop and start this instance and the problem goes away.

Our production environment relies on automatically launched and loaded 
instances via EC2 api.

Has anyone with knowledge of this particular ArangoDB AWS image an idea 
about what why it happens?


Thanks in advance
Soren
