Slow UI with Google Sheets

Questions
1

I’ve been experiencing significant performance issues with the n8n UI when processing a Google Sheets document containing 36,000 rows in a loop. This slowdown began after migrating to an Azure server with 32 GB of RAM and 8 vCPUs.

Interestingly, we didn’t encounter any UI freezing issues when running on a Hetzner server with only 4 vCPUs and 8 GB of RAM. Despite the increased resources on the Azure instance, the UI becomes unresponsive while the VPS is utilizing less than 10% of its capacity. I’ve tried running n8n in both Caddy mode and Docker Compose, adjusting CPU settings, but the problem persists.

I would appreciate any insights or recommendations to improve the UI performance.

  • Running n8n via (Docker, npm, n8n cloud, desktop app):
  • Operating system:

You can find some strategies to solve this in our documentation (even you don’t have an actual error, these will still help):
