#4 closed defect (duplicate)

Better eviction policy

Is there a better way to chose which swapfile should be decommissioned? One criterion is that we want to get back to our target state; the current greedy algorithm (pick largest swapfile <= ideal size) is the best way of achieving that. But we may want to minimize resulting swap activity instead. In that case we could pick the least-used swapfile.

Since swapfiles have different sizes, it's not so easy to make an initial selection based on size and then use usage as a tiebreaker. A compromise between them perhaps, such as picking a range of "good" sizes first and then choosing among them based on usage?
