When performing memory attacks in Gremlin, there are two options, percentage based and absolute amount.
Specifying an absolute amount is self explanatory. Specifying a percentage may result in unexpectedly high memory values during experiments as Gremlin by design calculates the percentage against the sum of total memory + total swap rather than just memory.
If you would prefer to exclude swap utilization from your experiments, you will need to specify absolute amounts of memory for your attacks.
In Linux, you can observe the total memory and swap via the free command.
In Windows, you can view the total 'Committed' memory (which is used to calculate percentages against) in the Memory portion of the 'Performance' tab in task manager.
