I recently noticed that on an Amazon t3a.large (2 VCPUs, 8GB RAM), whenever I hit publish of even a single page, celery spikes both CPUs to effectively 100% (or as much as they can take from other processes.)

I’m just wondering if this is expected, because celery just does a lot of work on publish? (Or whether it’s perhaps related to the [other issue](https://discuss.openedx.org/t/students-progress-page-doesnt-update-when-new-problems-are-added/9470/12) I’m having.)
