Troubleshooting inconsistent performance?

[etfz]

Hi,

I've been running a number of different NetBox versions over a few years, and for as long as I can remember, I've had issues with pages loading slowly, up to some ten seconds. On good days, pages load instantly, so the host clearly has the capacity. For example, just now I had the home page take ages to load, and then a couple of minutes later, it loads instantly. Sometimes it's somewhere in between. I think all pages might be affected at the same time, and it includes asynchronous requests such as for field autocomplete lookups.

I run a number of other Docker containers on the same host, and have never witnessed similar issues on any. Where can I start troubleshooting this?
