A few users reported IO-related issues during backup after upgrading to PVE 7.x and using a modified QEMU build with max-workers reduced to 8 instead of 16 helped them [0].
Other BackupPerf settings are not exposed, see the qemu patch for why. Introduces a more general 'performance' property string as a vzdump setting to be expanded in the future. And in the long run, existing performance settings like bwlimit could be moved into there. To detect if the currently running QEMU supports the setting, the query-proxmox-support QMP command is used. If not supported, a warning is printed and the setting is ignored. All but the last documentation patches are independent. The recently created dedicated section for jobs is expanded and the introductory section for backups is updated to mention PBS. The last patch mentions the new performance/max-workers setting.
