Dear All You Genius,
I previously used n8n as a self-hosted instance on Windows 11, paired with ngrok, and it worked flawlessly. Recently, due to an increase in AI-related work, I upgraded to a new computer and installed Ubuntu Desktop as the operating system. I’ve been using this setup for about a week now.
The new computer is equipped with high-performance hardware, including an NVIDIA 3090 GPU and 64GB of RAM—far more powerful than my old system. However, I’ve noticed some unexpected stuttering with n8n that wasn’t present in my previous Windows 11 setup.
Specifically:
Startup Delay: There’s about a 1-second delay when launching n8n, whereas it used to open instantly.
Node Editing Delay: Modifying data in a node takes around 3-5 seconds, which significantly slows down my work.
Although workflow executions themselves seem to be running fine, these delays are impacting my productivity and driving me a little crazy. 
I’m attaching the YAML configuration I’m using. It’s based on the self-hosted-ai-starter-kit, with some modifications I made by piecing together information from the internet and ChatGPT. Since I’m not a developer, my changes might not be optimal.
If anyone has a solution to these performance issues, I would greatly appreciate your help!
Thank you.
