Odoo performance issues in Amazon Web Services (EC2+RDS)

Avatar

Hello all, 

I'm currently testing odoo deployment in amazon web services. I have odoo installed in a ec2 instance and the database (Postgres) in a rds instance.

I'm starting the tests with the free-tier instances

ec2 - 1 CPU - 1GB Ram
rds - 1 CPU- 1GB Ram
Launching a test that confirms 800 invoices takes me around 8-9 minutes to complete

I'm assuming that the bottleneck is caused by the database, since the ec2 instance only has odoo which doesn't do the actual heavy-lifting in the requests.

When I upgrade the rds instance to 2 CPUs and 8 GB of Ram I can see a slight increase in performance, the same test now takes around 6 minutes to complete.

However, when I upgrade the rds instance to 16 CPUs and 122 GB of Ram the increase is almost unnoticeable compared with the previous setting, it takes around 5 minutes 30 seconds. 

Is the internal structure of Postgres not taking advantage of the extra CPU and Ram?

We are planning to implement our intranet with Odoo and we're looking at at least 50 concurrent conections at any given time, would the ec2 instance with 1CPU and 1GB of ram , with the rds instance of 2CPUs and 8GB of RAM be enough for that? 


Is there any way to increase Odoo's performance? Replicating databases might help with concurrent access but I'm not sure it's possible with Odoo+Postgres, should we use other databases?

The hardware you used is far beyond the recommended one so it should be more than sufficient. If you add CPUs you need to enable multi processing mode in order for odoo to make benefice of extra ones. Try running your server with the option --workers=12 and let's see how it goes for performance.

Understanding the needs of ecommerce business and to help them get necessary configurations and architecture. www.cloudways.com/blog/aws-for-ecommerce-applications/ platform provides its users with ready-to-use ecommerce architecture and blueprints in the form of AWS Cloud formation templates. These templates are provisioned to highly scalable and available infrastructure for hosting online stores.

Ecommerce web apps and platform providers such as Magento have noticeably published versions of their software to finetune to AWS architecture and integrate AWS monitoring and security processes.

Thanks Carlos for your great trial since I'm looking from something similar with this. Although I didn't test it, I can feel it is much slower when installing Odoo 9 onto T2.micro than T2.small with database on the same server.
