I have file storage backend, not consul but I’m also seeing very long times authenticating via “auth/approle/login”. 6 seconds is not a magic number for me it takes anywhere between 40 seconds and almost instantaneous response. At the same time navigating in the web UI does not feel sluggish or slow. I’d also like to find out how to diagnose this.
