Choosing the right server for Odoo

Odoo is most often deployed on Ubuntu VPS. Although this is suitable for most small scale installation with a few users, it isn't the right choice if you intend to use Odoo with a large number of users (>20) or if you are likely to have a fast growing database. In such cases, a dedicated server is recommended. Follow the rule of thumb below to select the right server for your Odoo.
Minimum #Workers required = #Users / 4
Minimum #Cores = (#Workers - 1) / 2

Minimum Memory required =  #Workers * ( (light_worker_ratio * light_worker_ram_estimation) + (heavy_worker_ratio * heavy_worker_ram_estimation) )

Configuring Postgresql for Odoo

Postgresql is installed with a default configuration file that needs to be edited based on the server and installation. The configuration file for postgresql is usually located at /etc/postgresql/main/version_number/postgresql.conf. We recommend using the PgTune utility to identify the optimum performance parameters for postgresql depending on your server.

Configuring Odoo and Reverse Proxy

Setting up Odoo behind a reverse proxy such as Nginx is recommended from security and performance perspectives. A sample configuration of nginx:

#odoo server
upstream odoo {
upstream odoochat {

# http -> https
server {
   listen 80;
   server_name odoo.mycompany.com;
   rewrite ^(.*) https://$host$1 permanent;

server {
 listen 443;
 server_name odoo.mycompany.com;
 proxy_read_timeout 720s;
 proxy_connect_timeout 720s;
 proxy_send_timeout 720s;

 # Add Headers for odoo proxy mode
 proxy_set_header X-Forwarded-Host $host;
 proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_set_header X-Forwarded-Proto $scheme;
 proxy_set_header X-Real-IP $remote_addr;

 # SSL parameters
 ssl on;
 ssl_certificate /etc/ssl/nginx/server.crt;
 ssl_certificate_key /etc/ssl/nginx/server.key;
 ssl_session_timeout 30m;
 ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
 ssl_prefer_server_ciphers on;

 # log
 access_log /var/log/nginx/odoo.access.log;
 error_log /var/log/nginx/odoo.error.log;

 # Redirect requests to odoo backend server
 location / {
   proxy_redirect off;
   proxy_pass http://odoo;
 location /longpolling {
     proxy_pass http://odoochat;

 # common gzip
 gzip_types text/css text/less text/plain text/xml application/xml application/json application/javascript;
 gzip on;

Enable multi-workers in the Odoo configuration file. For example, a server with 4 CPU and 3GB RAM, the configuration should be as follows:

limit_memory_hard = 1677721600
limit_memory_soft = 629145600
limit_request = 8192
limit_time_cpu = 600
limit_time_real = 1200
max_cron_threads = 1
workers = 8
prpxy_mode = True
