XOA High CPU / Single Core
-
I'm getting occasional alerts, through out the day, on my XOA VM for 90%+ CPU. It appears to be a single core that's going nuts. (Is XOA single threaded?). This is on a AMD Ryzen 3900X CPU. The pool has 40 Active VMs (across multiple servers).
Could this be a configuration issue?
I increased the RAM from 4GB to 6GB. Maybe more would help?
Not really an issue, but probably something worth investigating.

XO is build on using NodeJS. It's fast to do I/O because it's using an event loop (see https://nodejs.org/en/docs/guides/event-loop-timers-and-nexttick/ )
We are using workers for some tasks (backup merge) but most of the task are in a single process.
Also in your screenshot, there's a lot of traffic going on, so it might happen during a backup
-
Yes, definitely a backup running. I find XOA borderline unusable when I'm running backups, it doesn't matter how much horsepower I throw at it.
I would set up a proxy, but this is in my (high-end but still coming out of my pocket) home-lab.
-
Unusable is going too far. Noticeably slow, yes.
-
This will be far better in few releases
When new backup code used in the proxy will be merged into main XO code (so it won't block the event loop) -
Side note:
My bad. I built mine from source, so I should be referring to it as 'XO', not 'XOA'.
-
No problem
Proxy code will help a lot when merged in your main XO!
