Performance Issues Revealed

Is Odoo.sh Slow?

You are not imagining it. Users report Page Speed scores as low as 28/100 and have migrated customers away due to performance issues. Shared hosting, worker limits, and no caching options are the real culprits.

Why Is Odoo.sh Slow?

The technical reasons behind Odoo.sh performance problems

Shared Hosting Architecture

Odoo.sh runs multiple customers on shared infrastructure by default. Your performance depends on other tenants' usage patterns. During peak times, you compete for CPU, memory, and I/O with other businesses.

Worker Limits on Shared Plans

Each Odoo worker handles one request at a time. Shared plans have strict worker limits. When all workers are busy, additional requests queue up, causing visible lag for users.

No PostgreSQL Tuning Control

Database performance is critical for Odoo. Odoo.sh uses default PostgreSQL settings without letting you tune shared_buffers, work_mem, or connection pooling for your workload.

No Redis Caching Option

Redis caching can dramatically speed up Odoo by caching sessions, computed fields, and frequent queries. Odoo.sh does not offer Redis as an option on shared plans.

No Custom Nginx Configuration

Nginx configuration impacts static asset serving, gzip compression, and connection handling. Odoo.sh does not allow custom Nginx tuning for your specific needs.

Geographic Latency

Odoo.sh servers are in limited locations. If your users are far from these data centers, every request suffers from network latency that adds up across page loads.

The Compound Effect

These issues compound on each other. Shared hosting means less resources, which means slower queries, which means workers are busy longer, which means request queuing. Without Redis to cache results, every request hits the database. Without PostgreSQL tuning, queries are slower than necessary. The result: Page Speed scores of 28-40/100 and frustrated users.

Resource Contention: The Hidden Problem

On shared hosting, your Odoo instance competes with other tenants for every resource. Here is how resource contention directly impacts your performance.

CPU Contention During Peak Hours

When multiple tenants run heavy operations simultaneously - reports, imports, scheduled actions - your instance competes for CPU cycles. This results in longer response times and timeouts during business-critical hours.

Impact: 2-10x slower response times

Memory Pressure from Neighbors

Shared memory pools mean other tenants' memory-intensive operations can trigger OOM conditions affecting your instance. PostgreSQL connections may be killed, causing transaction failures.

Impact: Intermittent errors and crashes

I/O Bottlenecks on Shared Storage

Database writes, file uploads, and backup operations all compete for disk I/O. When neighbors run large imports or backups, your instance's database queries slow significantly.

Impact: Database query timeouts

Network Bandwidth Sharing

Large file transfers by other tenants can saturate network capacity, slowing down API responses, webhook deliveries, and static asset loading for your users.

Impact: Slow API and file downloads

Dedicated Hosting Eliminates Resource Contention

With OEC.sh, you get 100% dedicated resources. No noisy neighbors, no resource competition, no unpredictable performance spikes. Your server resources are yours alone, delivering consistent, predictable performance for your users.

Frequently Asked Questions

Common questions about Odoo.sh performance issues

Why is Odoo.sh slow?

Odoo.sh uses shared hosting architecture by default, meaning your instance shares CPU, memory, and I/O with other customers. Combined with worker limits, no Redis caching option, and default PostgreSQL settings, this leads to performance issues especially during peak usage. Users report Mobile Page Speed scores as low as 28/100 and significant slowdowns after upgrades.

How can I make Odoo.sh faster?

On Odoo.sh, your options are limited. You can upgrade to dedicated hosting (adds $600/month), optimize your code and database queries, reduce installed modules, and use CDN for static assets. However, you cannot implement Redis caching, tune PostgreSQL, or customize Nginx on shared plans. Switching to dedicated hosting like OEC.sh gives you full control over performance optimization.

What is a good Page Speed score for Odoo?

A properly optimized Odoo installation should achieve Mobile Page Speed scores of 70-90/100. Odoo.sh users commonly report scores of 28-50/100. On OEC.sh with proper configuration, Redis caching, and PostgreSQL tuning, scores of 80-95/100 are achievable. This directly impacts user experience and SEO rankings.

Why is Odoo.sh slow on mobile?

Mobile performance suffers more from Odoo.sh limitations because mobile devices have less processing power for JavaScript, are often on slower networks, and are more sensitive to latency. The lack of Redis caching, suboptimal asset bundling, and geographic distance to servers all compound on mobile. Users frequently report that Odoo.sh is 'far too slow on mobile'.

Does upgrading Odoo version affect performance?

Yes, major Odoo upgrades often cause performance issues on Odoo.sh. Users report significant slowdowns after upgrading to Odoo 17 and later versions. New features and changed ORM behavior require more resources, but Odoo.sh's shared hosting does not automatically scale to meet these demands.

Can I use Redis with Odoo.sh?

No, Odoo.sh shared plans do not offer Redis caching. Redis is a powerful tool for caching sessions, HTTP responses, and computed fields that can dramatically improve Odoo performance. With OEC.sh, you can easily add Redis to your stack and configure it for optimal caching.

How much faster is dedicated Odoo hosting?

Dedicated Odoo hosting like OEC.sh typically delivers 2-5x faster page loads compared to Odoo.sh shared hosting. The improvement comes from 100% dedicated resources, Redis caching, PostgreSQL tuning, and the ability to deploy close to your users. Page Speed scores commonly improve from 28-40 to 80-95.

Is migrating from Odoo.sh to faster hosting difficult?

Migration from Odoo.sh to OEC.sh is straightforward and typically takes 2-4 hours. Export your database backup, import to OEC.sh, connect your code repository, and update DNS. We provide free migration assistance with Pro and Agency plans, and you will see immediate performance improvements.
