Re: Quincy recovery load

Do you mean load average as reported by `top` or `uptime`?

That figure can be misleading on multi-core systems.  What CPU are you using?

For context, when I ran systems with 32C/64T and 24x SATA SSD, the load average could easily hit 40-60 without anything being wrong.

What CPU  percentages in user, system, idle, iowait do you see?
