Looks like your problem is this one: [Reschedule sidekiq scheduled job](https://meta.discourse.org/t/reschedule-sidekiq-scheduled-job/90805)

You have one still active topic (last reply 19m ago) with 17k posts. That plus slow disks kill performance. The fact that your data is larger than the RAM also makes this more complicated.
