If using XO from Source - How much ram are you assigning
-
So I have a backup job running, this is all fine and dandy, the question comes in how much ram should I expect to assign to XO so that the environment feels usable. Here is top utilization of node, for Xen Orchestra's service.
This VM has 12 GB of ram and 6 vCPU, and the backups are still taking quite a while to complete.
Obviously pegging the XO resources out would cause performance issues, but besides throwing literally everything I have at XO, how are others achieving backups in a timely window?
It could of course be a factor of the source/destination IOPS, I unfortunately don't have a great way to pull this metric to verify (at least that I've found).

12GiB is far more than enough. Depending on the size of your infrastructure, it's maybe even overkill. Check https://xen-orchestra.com/docs/troubleshooting.html#memory

@olivierlambert yeah, I bumped it to that, because at 4GB I had 20MB left while a backup operation was occurring.

Of real RAM usage? Eg with
htop, take care of the cache too, because even if the cache is used doesn't mean it's really important. Maybe 8GiB is enough for example.
