[pve-devel] tasks / ressources

[Alexandre DERUMIER]

Also, I don't known for you, but my pvestatd daemon refresh values each 10 seconds.
So why pve-manager is pooling each second ?

I have around 50vms on this host, 
Polling vm status is fast, but the storage status take around 2s (could be great have a seperate worker/thread/something parallel for this)
But after that it's waiting 7s.

(My main problem is that I can see noticable delays when start/stop vms)

Not really but latency / load time of the current / tasks is checkable. So if it takes 1s it doesn't make sense to query it every s.
