There are a few settings for tuning backup performance (some of which are
exposed in the 'Advanced' tab in the UI). The most notable is `bwlimit` for
limiting IO bandwidth. The amount of threads used for the compressor can be
controlled with the `pigz` (replacing `gzip`), respectively, `zstd` setting.
Furthermore, there are `ionice` (when the BFQ scheduler is used) and, as part of
the `performance` setting, `max-workers` (affects VM backups only) and
`pbs-entries-max` (affects container backups only). See the
xref:vzdump_configuration[configuration options] for details.
