+Specify a minimum migration ratio to trigger a rebalancing
|
|
+Normally any improvement in load distribution will trigger the migration of an
|
|
+irq, as long as preforming the migration will not simply move the load to a new
|
|
+cpu. By specifying a migration value, the load balance improvement is subject
|
|
+to hysteresis defined by this value, which is inversely propotional to the
|
|
+value. For example, a value of 2 in this option tells irqbalance that the
|
|
+improvement in load distribution must be at least 50%, a value of 4 indicates
|
|
+the load distribution improvement must be at least 25%, etc
