If you prefer you can configure the channels in your odoo.cfg, as explained in the README.

[Performance Issues]

When i changed from root:2 to root:1 , My CPU usage cross the 80 - 85%(closer to last job) for two users only.
When users limit exceed (more than 5) server stopped.
How can i prevent it ?

For ex.
100 Jobs are in pending state. CPU Usage goes 5-10% (Upto 80 Jobs). But after cross 80 CPU Usages exceed 80 - 90 (100 Jobs are doing same action for different users)

from queue.

Hi @sbidoul after change the channel capacity 1, process run normally and i cannot get any concurrent error in my local machine. But In server side, i'm getting the concurrent error repeatedly. Even if i requeue the process, again getting concurrent issue. Now in my situation, Performance not a issue.
If workers is 0, what happened that time ?
