sudo apt update && sudo apt -y install elasticsearch
sudo zammad run rails r “Setting.set(‘es_url’, ‘http://localhost:9200’)”
sudo zammad run rails r “Setting.set(‘es_attachment_ignore’, [ ‘.png’, ‘.jpg’, ‘.jpeg’, ‘.mpeg’, ‘.mpg’, ‘.mov’, ‘.bin’, ‘.exe’, ‘.box’, ‘.mbox’ ] )”

Try to increase your RAM according to the Zammad hardware prerequisites, which is at least 4GB.

Increased RAM to 4GB but still slow as before.

What storage is below your Zammad-Instance?
Also, how many Agents do you have?

What processes are eating up your RAM?

Also, for elasticsearch, the following document might help you:

We just pushed even more ram Into ist and now it works.
Sometime things can be easy
