CPU load and performance issues

To do in order, until the problem is solved:

  • check the number of connected pools/hosts
  • try disabling usage-report plugin
  • increase XOA memory: https://xen-orchestra.com/docs/troubleshooting.html#memory

  • increase the latency for fetching XAPI updates: in /etc/xo-server/config.xapiOptions.toml:

    [xapiOptions]
    debounce = 1e3 # 1 second
    
  • if huge number of pools, try splitting on multiple XOAs (an XOA trial can be provided to the customer)
