Hi @Thomas Kempson 

yes, you are right - out -of -systems require minimal 4GB RAM, but in practice, especially for local development Service Studios, Service Center, and using individual environment/local installations, you can increase significantly based on your use (e.g. large modules, agents, devices).

You have mentioned 16GB RAM, which is actually a solid layout. To avoid the use of high memory or gap, here are some fantasy recommendations and tips that can help:

✅ Suggested glasses (for smooth outsystems development):

RAM: 16 GB (you are good here but 32 GB is ideal if many World Cups or parallel tools are running)

CPU: I5 (11. Gen or later) or Ryzen 5000 series and above (preferably four core or higher)

SSD: At least 512 GB NVME for fast start -up and application loading

OS: Windows 10/11 64-bit (prioritized for Hyper-V if necessary)

GPU: Integrated graphics are good until you use Figma/Adobe XD

🛠 tips to reduce memory use:

Limit the module simultaneously Open in the service studios

Disable Background apps as doctors, vs -codes, browser when not in use

Unused tab in service studio and close the atmosphere

Use task manager or Process explorer.

Think about Switch to the web Traditional if you work with big reactive apps, as reactive apps use more resources

🧪 Optional:

Enable Outsystems Lifetime/Service Center on a separate server or World Cup.

Add a Ram Cleaner tool to Windows or twenty virtual memory settings in windows.

Thank you
