…ser-friendly info flow. Provide a range of better code/functionality examples modified: docs/throttling-backups.md
| When specified with the `--backup` option, this option | ||
| limits the number of pairs of read-and-write operations per second that | ||
| *xtrabackup* will perform. If you are creating an incremental backup, then the limit is the number of read I/O operations per second. | ||

This section should be in one of the beginning sections. I need to know how it behaves.

| The following diagram illustrates throttling with `--throttle=1`. |

The image conveyed nothing to me. I looked at it several times to see if I could figure it out.

| The `--throttle` option limits the number of **10 MB chunks** processed per second. |

Use the --throttle option to minimize backup impact on system performance. By limiting the number of 10 MB chunks processed per second, you effectively throttle both the total data throughput and the resulting IOPS.
| can add load to the system being backed up. On systems that do not have | ||
| much spare I/O capacity, it might be helpful to throttle the rate at which | ||
| *xtrabackup* reads and writes data. You can do this with the [--throttle] option. This option limits the number of chunks copied per second. The chunk +size is *10 MB*. | ||
| xtrabackup does not block database activity during a backup, but it generates additional disk input/output (I/O) activity. On systems with limited I/O capacity, this can affect database performance. |
