Odoo 11 Workers

Question

I cant figure out how to use workers in Odoo. I have a Server setup with ubuntu 16.04. nginx is installed and working.

My server will be running two databases. it has 16GB ram installed. This will be used by no more than 10 users.

Sever Cpu specs are 
Architecture:          x86_64
CPU op-mode(s):        32-bit, 64-bit

On-line CPU(s) list:   0-7

L3 cache:              8192K
NUMA node0 CPU(s):     0-7

My odoo-server conf is just standard as I am not sure what values to put in.

[options]
; This is the password that allows database operations:
admin_passwd = **********
xmlrpc_port = 8069
logfile = /var/log/odoo/odoo-server.log
addons_path=/odoo/odoo-server/addons,/odoo/custom/addons

In my experience, an Odoo server with 5-6 workers is fine for a 10-user setup

You'll need:

• 1 for the main thread
• 1 to 3 HTTP processing
• 1 for Cron processing
• 1 for PDF processing

Most of the code related to workers is in <path_to_v11>/odoo/service/server.py, you may want to read it.

Also, have a look at https://www.odoo.com/documentation/11.0/reference/cmdline.html to find the config/command line options.

In particular,

--workers <count> if count is not 0 (the default), enables multiprocessing and sets up the specified number of HTTP workers (sub-processes processing HTTP and RPC requests).

multiprocessing mode is only available on Unix-based systems

--limit-request <limit> Number of requests a worker will process before being recycled and restarted.

Defaults to 8196.

--limit-memory-soft <limit> Maximum allowed virtual memory per worker. If the limit is exceeded, the worker is killed and recycled at the end of the current request.

Defaults to 2048MiB.

--limit-memory-hard <limit> Hard limit on virtual memory, any worker exceeding the limit will be immediately killed without waiting for the end of the current request processing.

Defaults to 2560MiB.
