New to eyeballing `top` in freebsd, but facing a situation where nothing really sticks out, but still suspicious.
Running `restic`, which is performing its initial backup, and for that performs an initial read and checksumming of all files. Of course, it is possible that restic itself acts up, but I would like to know if that is something I should investigate, or there's some other more obvious sign in system resource usage that I'm missing.
Edit: maybe I missed something obvious - maybe it was doing upload to cloud storage interleaved with the file scanning, which I assumed would happen as a second step. Is there a tool I could use to get statistics about open connections and the transfer that happened on them? sockstat gives some info, but it doesn't seem to have a running sum of transfer (something I recall Linux's iotop had).
`gstat` shows mostly zero IO activity. `lsof -p`-ing restic shows the same few files open for many seconds, which seems a sign of slow processing. But CPU is almost unused. `top` io mode (m) shows VCSW of restic in 1K-3K range.
On one hand would have assumed I'm a bit short on RAM, on the other hand I don't see any swapping going on.. thank you for any insights!
