Performance

The default settings of Wazo are sufficient for low-traffic environments. However, higher traffic may require some modifications to improve the performance or quality of calls.

Increase the number of concurrent requests

Wazo services can handle multiple requests concurrently. The setting max_threads will define the number of threads and database connections that Wazo daemons will keep ready for processing requests.

Since this setting increases the number of database connections, you may also have to increase the maximum number of database connections. By default, Wazo uses a maximum of about 50 connections and PostgreSQL accepts a maximum of 100 connections.

For example, to modify the number of concurrent requests:

1. If needed, increase the number of maximum database connections by editing /etc/postgresql/13/main/postgresql.conf:

max_connections = 200

2. Then restart the database and all services to apply the change:

wazo-service restart all

3. Increase the number of concurrent requests for wazo-chatd (for example) by creating a new file /etc/wazo-chatd/conf.d/50-threads.yml:

rest_api:
  max_threads: 25

4. Then restart the service to apply the change:

systemctl restart wazo-chatd
