The code itself is generic and independent of the I/O 14 and operations per second (IOPS) when performing disk I/O. 20 Using throttling to limit disk I/O 22 Two aspects of the disk I/O can be limited: the number of bytes per 27 I/O limits can be set using the throttling.* parameters of -drive, or 71 I/O bursts 74 user to do bursts of I/O for a configurable amount of time. A burst is 75 an amount of I/O that can exceed the basic limit. Bursts are useful to 81 I/O they allow. These two can be configured separately for each one of 85 The I/O limit during bursts is set using 'iops-total-max', and the [all …]

This is particularly true with solid state drives 208 memory usage during periods of low I/O activity.
