    Description

      It appears that high CPU is due to swapperDaemons checking whether to evict or not every 1ms (EvictRunInterval). Instead of sleeping for constant duration, would sleeping using a DecayInterval (sleep duration increases every time we decide not to evict upto 1s) help here github.com/couchbase/plasma/blob/master/swapper.go#L165?
