We're facing major slowdowns with Odoo Community v14 when doing heavy tasks like exporting multiple purchase orders to PDF, approving POs, or importing files. The system freezes, lags badly, and blocks other users from working. This happens on both physical and virtual servers with powerful AMD EPYC or Intel Xeon Platinum CPUs.

Oddly, when we run Odoo on regular Intel i5 or i7 servers, everything works smoothly—no freezes, no lags, and multiple users can work fine.

Details:

Odoo 14 (Docker Compose)

PostgreSQL 13

Physical host: Intel Core i5, 16GB RAM (runs smooth)

VPS host: AMD EPYC 32 cores, 32GB RAM (runs slower, despite bigger specs)

Tested with same Docker image and volumes (no changes)

About 20 active users + 4 POS terminals

We've tried:

- Checking server resources (CPU, RAM, storage) for issues.

- Tweaking Odoo settings for workers and polling.

- Testing on different hosting providers.

- Applying the latest Odoo v14 updates.

Why does Odoo struggle on high-end servers but run well on consumer PCs? Could it be related to CPU differences or Odoo’s setup? Has anyone seen this issue or found a fix? Any advice on optimizing Odoo or server settings would be greatly appreciated!
