Einführung
We ran a speed test on a client’s Odoo eCommerce store last month. The homepage took 6.8 seconds to load on mobile. Six point eight. They were losing visitors before the first product image even showed up. And the worst part? Their Odoo installation was barely six months old. The platform wasn’t broken. The Odoo speed optimization just never happened after launch.
This is more common than you’d think. Odoo ships with default configurations that work fine for demos but choke under real traffic with real product catalogs. If your Odoo website is slow, it’s probably not an Odoo problem. It’s a settings problem, a hosting problem, or a “nobody cleaned the database in 18 months” problem.
Below are 10 tricks we’ve used on actual client stores. Ranked from five minute quick wins to advanced server tuning. Every single one has been tested on US based Odoo deployments running real eCommerce traffic.
How Do I Check My Odoo Website Speed?
Before you fix anything, figure out where you actually stand. Run your homepage through Google PageSpeed Insights. Then run a product page. Then your checkout. Write down the numbers. Here’s what you’re aiming for with proper Odoo page speed optimization:
| Metrisch | Gut | Needs Work | Arm |
|---|---|---|---|
| LCP (Largest Contentful Paint) | Under 2.5s | 2.5 to 4s | Over 4s |
| INP (Interaction to Next Paint) | Under 200ms | 200 to 500ms | Over 500ms |
| CLS (Cumulative Layout Shift) | Under 0.1 | 0.1 to 0.25 | Over 0.25 |
| TTFB (Time to First Byte) | Under 800ms | 800ms to 1.8s | Over 1.8s |
One more thing. Turn on Odoo’s built in Debug Profiler. It shows you exactly which modules and database queries are eating up time. You’ll be surprised how often one forgotten module accounts for half your load time.

Trick 1: Enable Asset Bundling and Minification
Why Is My Odoo Website Slow After Installation?
Fresh Odoo installs run with debug mode on and every CSS and JavaScript file loading separately. That’s dozens of HTTP requests on every single page load. Turning debug mode off and enabling asset bundling is the fastest way to speed up your Odoo website. Five minutes of work. 20 to 30% faster immediately. Go to Settings, turn off developer mode, and let Odoo bundle your assets.
Trick 2: Optimize and Compress Images
How Do I Reduce Image Load Time on Odoo?
We pulled up a client’s product page last year and the hero image alone was 4.2MB. One image. Four megabytes. That’s why the page took forever. Images typically make up 60 to 80% of an Odoo page’s weight. Here’s what to do about it:
Convert to WebP format. Odoo 17 and above handle this natively
Turn on lazy loading so images below the fold only load when someone scrolls there
Compress before uploading. TinyPNG or Squoosh. Takes 30 seconds per batch
Cap product images at 8 to 12 per page. Enough detail, not enough to crash the browser
Trick 3: Upgrade to Python 3.12+ and Odoo 18 or 19
Does Upgrading Odoo Version Improve Speed?
Short answer: yes, and sometimes dramatically.
- Python 3.12 runs about 25% faster than 3.10 without you changing a single line of code
- Odoo 18 and 19 brought ORM improvements, a leaner asset pipeline, and the new Hummingbird frontend that drops a bunch of legacy bloat
- If you’re still on Odoo 16 with Python 3.8, the upgrade alone might solve half your speed complaints
- AWS and DigitalOcean both support Python 3.12 on their current US server images
Trick 4: Configure PostgreSQL Properly
What PostgreSQL Settings Should I Use for Odoo?
This is the trick that makes the biggest difference and almost nobody does it. PostgreSQL ships with settings designed for a laptop running a small test database. Your production Odoo store with 50,000 products and three years of order history needs very different numbers. Here’s what proper Optimierung der Odoo Datenbank looks like:
| Parameter | Standard | Recommended for Odoo |
|---|---|---|
| shared_buffers | 128MB | 25% of total RAM |
| work_mem | 4MB | 64MB |
| effective_cache_size | 4GB | 50 to 75% of RAM |
| maintenance_work_mem | 64MB | 512MB to 1GB |
| max_connections | 100 | 200 (with PgBouncer) |
We’ve seen stores go from 4 second TTFB to under 800ms just by fixing these five settings. Nothing else changed.
Trick 5: Set Up Odoo Workers Correctly
How Many Workers Does My Odoo Server Need?
There’s a simple formula for Odoo performance optimization at the worker level: take your CPU core count, multiply by 2, add 1. So a 4 core server gets 9 workers. Set memory limits on each worker so one runaway process can’t crash your entire server. And allocate 1 to 2 cron workers separately from your HTTP workers. Don’t let a scheduled report generation steal resources from a customer trying to checkout.
Trick 6: Implement Redis for Sessions and Cache
Should I Use Redis or Memcached for Odoo?
- File based sessions work fine when you’ve got one worker. The second you scale to multiple workers, they become a bottleneck.
- Redis fixes this. It stores sessions in memory, handles object caching, and cuts your database load by 30 to 40% on repeat visits.
- Memcached vs Redis? Redis wins for Odoo. It supports persistence and richer data structures that Odoo’s caching layer actually uses.
- This is one of those Odoo performance optimization moves that pays off immediately and keeps paying off as traffic grows.
Trick 7: Clean Your Database Every Month
Does Cleaning Odoo Database Improve Performance?
Odoo hoards data like nobody’s business. Server logs pile up. Abandoned carts sit there for years. Mail queue entries from 2023 are still taking up space. All of that drags your Optimierung der Odoo Datenbank efforts down. Here’s what to clean and how often:
| Table | What to Clean | How Often |
|---|---|---|
| ir_logging | Server logs | Weekly |
| ir_attachment | Orphaned files nobody uses | Monatlich |
| sale_order (draft) | Abandoned carts | Monatlich |
| mail_message | Old internal chats and notifications | Quarterly |
| website_visitor | Anonymous visitor tracking data | Monatlich |
Set up a cron job for this. If you’re doing it manually you’ll forget by month two. We all do.
Trick 8: Use a CDN for Static Assets
Do I Need a CDN for My Odoo Website?
- If your server sits in Virginia and a customer in Los Angeles loads your store, that data travels 2,500 miles each way for every image, CSS file, and JavaScript bundle.
- A CDN caches that stuff on servers closer to your visitors.
- For US stores specifically, Cloudflare’s free tier works surprisingly well.
- AWS CloudFront is the step up if you’re already on EC2.
- Configure it in Odoo under Settings > Website > CDN.
- This is Odoo page speed optimization that takes 30 minutes and works 24/7 after that.
Trick 9: Audit and Remove Unused Modules
How Many Modules Are Too Many on Odoo?
A client came to us last quarter with 47 modules installed. They were actively using 19 of them. The other 28 were adding hooks, running background queries, and loading JavaScript on every single page for absolutely no reason. Run the Odoo profiler. Find anything taking over 100ms per request. Uninstall it. Don’t just deactivate, actually uninstall and delete the folder. Our rule: if a module hasn’t been touched in 90 days, it goes.
Trick 10: Switch to Performance Optimized US Hosting
What Is the Best Hosting for Odoo in the United States?
We’ve said this a hundred times and we’ll say it again. Shared hosting is the number one reason Odoo websites run slow in the US. You’re sharing CPU, RAM, and disk I/O with dozens of other sites. One neighbor’s traffic spike and your checkout page takes 8 seconds. Here’s what actually works for Odoo in the United States:
| Partner | Type | US Region | Startpreis | Odoo Ready |
|---|---|---|---|---|
| AWS (EC2) | Cloud VPS | US East (Virginia) | ~$35/mo | Ja |
| DigitalOcean | Cloud VPS | NYC, SFO | $24/mo | Ja |
| Linode (Akamai) | Cloud VPS | Newark, Dallas | $24/mo | Ja |
| Hetzner Cloud | Cloud VPS | Ashburn, VA | $7/mo | Ja |
| Odoo.sh | Managed PaaS | Multi region | $72/mo | Einheimisch |
Minimum specs you should never go below: 4 vCPUs, 8GB RAM, NVMe SSD, Python 3.12+. Server physically located in the US. That last part matters more than most people realize.
What Each Trick Actually Delivers
Here’s the cheat sheet. Every trick ranked by how much speed you gain versus how hard it is to implement:
| Trick | Avg Speed Gain | Difficulty | Time |
|---|---|---|---|
| Asset bundling | 20 to 30% | Easy | 5 min |
| Image optimization | 20 to 30% | Easy | 30 min |
| Python/Odoo upgrade | 15 to 25% | Medium | 2 to 4 hrs |
| PostgreSQL tuning | 25 to 40% | Medium | 1 hr |
| Worker config | 20 to 35% | Medium | 30 min |
| Redis caching | 30 to 40% | Erweiterte | 1 to 2 hrs |
| Database cleanup | 10 to 20% | Easy | 30 min |
| CDN setup | 15 to 25% | Easy | 30 min |
| Module cleanup | 10 to 25% | Medium | 1 to 2 hrs |
| Better hosting | 40 to 60% | Medium | 2 to 4 hrs |
If you’re looking for the fastest wins, start with tricks 1, 2, and 7. Five minutes for asset bundling. Thirty minutes for images. Another thirty for a database cleanup. You’ll see results before lunch.

Start with the tricks that need zero coding. Turn off debug mode and enable asset bundling. Compress your images with TinyPNG before uploading. Clean out your database logs and abandoned carts. Set up Cloudflare's free CDN. Those four things alone can shave 2 to 3 seconds off your load time and none of them require touching a line of code.
Under 2.5 seconds for your Largest Contentful Paint. That's Google's threshold for "good." US shoppers on mobile, especially on 4G, will bounce at 3 seconds without thinking twice. Get your LCP below 2.5 and your TTFB below 800ms and you're in solid shape.
Noticeably, yes. The Hummingbird frontend is lighter, the asset pipeline processes faster, and the ORM has been tightened up for common queries. We measured a 15 to 20% improvement on a client's product catalog pages after upgrading from 18 to 19 with identical content and hosting.
Odoo.sh comes reasonably well optimized out of the box. But it's less flexible than self hosted. A properly tuned VPS on AWS or DigitalOcean with the right PostgreSQL settings, Redis caching, and worker config can outperform Odoo.sh, especially for high traffic US stores. Odoo.sh is great if you don't want to manage infrastructure. Self hosted wins if you want maximum control over performance.
Absolutely. The US is huge. If your server is in Virginia and your customer is in Seattle, that's still 2,500 miles of latency on every asset request. Cloudflare's free tier caches static files on edge servers across the country. We've seen 200 to 400ms improvement on West Coast load times from an East Coast origin just by flipping Cloudflare on.
Logs and visitor data? Monthly, at minimum. Abandoned carts and orphaned attachments? Also monthly. Old mail messages and internal notifications? Once a quarter is fine. The key is automating it with a cron job. Manual cleanup works the first time. By month three you'll have forgotten about it and the database bloat creeps right back.
Letzte Gedanken
Speed isn’t a vanity metric. Every second your Odoo store takes to load is a customer who almost bought something but didn’t. Start with the easy wins: asset bundling, image compression, and a database cleanup can happen this afternoon. Then schedule a weekend for PostgreSQL tuning and hosting evaluation. For US based Odoo stores, hosting on a US server and configuring PostgreSQL correctly delivers the single biggest Odoo speed optimization improvement you’ll make all year.
