      Hi!
      I have two DELL PE2950 servers with E5430@2.66GHz processors 32GB, both running XCP-ng 8.2.1.
      I'm having issues with virtual machines performance.
      I use local storage.

      Its unsupported CPU?
      The problem manifests itself when accessing individual files (or threads?), and is visible in top as approximately equal values ​​for %user and %system. %wait is close to zero (meaning it's not an I/O issue).
      At the same time, on the hypervisor side, xentop shows load spikes up to 100% VM utilization.
      The problem is easily reproducible using acme.sh.
      The simple command acme.sh list takes seconds to execute inside the VM, but runs very quickly inside the hypervisor's bash shell.

      Help please!
