Sorry to bother everyone, but when running node red using WSL on Windows 11, it takes a long time to load Palette nodes. It usually takes more than 30 seconds. I searched on Google and forums but couldn't find the answer.

I have 15 dependancies in /home/steve/.node-red/package.json

show us what is in /home/xty18/.node-red/package.json
- cat /home/xty18/.node-red/package.json
How much memory does your computer have
- Are you hitting virtual memory) ?
Is your CPU usage high?
- before launching node-red?
- while launching node-red?

Also, if you set the log level to Trace in settings.js then I think you may see what is taking the time.

Your flow credentials file is encrypted using a system-generated key.

If the system-generated key is lost for any reason, your credentials
file will not be recoverable, you will have to delete it and re-enter
your credentials.

You should set your own key using the 'credentialSecret' option in
your settings file. Node-RED will then re-encrypt your credentials
file using your chosen key the next time you deploy a change.

these are quite odd. I would bet money that one or all of these are responsible for the slow loading.

Did you add these yourself? Have you ever opened your firewall/router to permit in-bound connection to your Node-RED? Is your Node-RED secured?

The last one Modbus_sia suggests you are trying to work with Modbus stuff? There are installable nodes designed for modbus (open the palette manager and search for node-red-contrib-modbus).

Thank you for your reply.
These are all packages that I have customized and developed myself. Thank you for the prompt. I will comment out these packages and observe the loading time.
What do security issues refer to? How to adjust security issues since the operating environment is WSN and the host is Win11?
