Hi! Thanks for reporting.

It would be great if you told us more. Like what you mean with high cpu load, when this happens, and what you make of the profile.

Hi Peter,

This issue was automatically authored by my VSCode IDE, and as a layperson I couldn't interpret the profiling it generated.

However, during this high load event, what I experience is that the Calva REPL becomes unresponsive to Option+Enter (MacOS). This happens periodically and I often wonder if it is because the Calva REPL history is running into the 1000s of lines. But deleting the previous lines in the file doesn't have an immediate effect. I have to restart the REPL most of the time.

It sounds like the structural editor runs into problems. I'll see if the profile report can tell me anything more about it.

Thanks for looking. If you don't find anything then I don't mind you closing the issue, as the workaround of restarting the REPL is not too burdensome so far.

As I say, my IDE wanted the issue raised 🤖. Here is its documentation for doing so.

It's interesting that it helps restarting the REPL. I recognize that from some other issue. Could mean that I am wrong about this being related to the structural editor.
