The adoption of ERP software It is one of the most significant strategic steps for any growing company. In the Catalan business environment, the search for a Odoo Partner in Barcelona has skyrocketed thanks to the modular flexibility and maturity of this ecosystem. However, many small and medium-sized businesses face a critical dilemma: the standard per-user subscription model in shared clouds can drive operating costs up to unaffordable levels as the workforce expands.
In this technical guide prepared by the engineering team at Synergia, we analyze the ideal architecture for the Odoo ERP Implementation in dedicated servers their own, using containers Docker and orchestration with Docker Compose. This infrastructure guarantees latencies of less than 50 ms, full data sovereignty, and the complete elimination of per-workstation licenses.
Adopting ERP software represents a pivotal strategic milestone for any growing company. Across the Catalan business landscape, demand for a specialized Odoo Partner in Barcelona has surged due to Odoo's modular flexibility and the maturity of its ecosystem. However, many SMEs face a critical obstacle: standard per-user cloud subscription models cause operating costs to rise unsustainably as teams grow.
In this technical guide from the Synergia As an engineering team, we analyze the optimal architecture for deploying Odoo ERP Implementation on dedicated bare-metal servers using Docker and Docker Compose. This infrastructure guarantees query response times under 50 ms, complete data sovereignty, and the complete elimination of per-user license fees.

Compared to the multi-tenant instances of Odoo Online or Odoo.sh, opt for a dedicated server Managed cloud solutions offer structural advantages that are unattainable in overcrowded public clouds:
- Performance Without Resource Containment (Noisy Neighbors): All CPU cores (AMD EPYC or Intel Xeon), ECC RAM, and NVMe storage IOPS are dedicated exclusively to your Odoo database and workers.
- Strict regulatory compliance and GDPR compliance: Your data is physically stored on certified European infrastructure, which eliminates the need for international data transfers and facilitates cybersecurity audits.
- No recurring costs per user license: When you deploy Odoo on your own servers, you can grant access to 20, 50, or 500 employees without paying a single additional euro per user per month.
- On-site and remote SysAdmin support in Barcelona: Immediate support from specialized systems engineers with an SLA of less than 2 hours.
Compared to multi-tenant shared environments such as Odoo Online or Odoo.sh, choosing a managed dedicated server offers structural advantages that cannot be achieved on public clouds:
- Performance with zero resource contention (Noisy Neighbors): Dedicated CPU cores (AMD EPYC or Intel Xeon), ECC RAM, and NVMe IOPS are dedicated solely to your database and Odoo worker processes.
- Strict compliance with the GDPR and European regulations: Your company's data is physically stored in certified European data centers with audit-ready security guarantees.
- Zero recurring per-user licensing fees: Deploying on bare metal allows you to onboard 20, 50, or 500 employees without paying any additional per-user software fee.
- Direct SysAdmin engineering support in Barcelona: Prompt remote and in-person support with a strict SLA of less than 2 hours from certified systems engineers.

In incident 90% of the Slow Odoo instances, the issue stems from a default PostgreSQL configuration. On dedicated servers with 32 GB or 64 GB of RAM, applying parameters such as shared_buffers, work_mem And optimizing Autovacuum increases the speed of generating accounting reports and inventory queries tenfold.
In over 90% of slow Odoo instances, the default PostgreSQL configuration parameters are the root cause of the bottleneck.
