Regarding the issue of webpage crashes when running workflows

I’m a junior developer and I’ve built a workflow with 270 nodes for document generation. Currently, it relies on stacked prompts and a large language model without any database integration. Backend data is passed in JSON format. The workflow contains about 54 model nodes combined with prompt nodes. When running this workflow, the n8n interface becomes very laggy and eventually crashes after a while. What could be causing this issue?

I suggest you to use sub-workflows and make the workflow smaller. Otherwise, you should have a lot of free memory for your browser
