This is encouraging.
>> On Chrome OS, our real-world benchmark that browses popular websites in multiple tabs demonstrates 51% less CPU usage from kswapd and 52% (full) less PSI on v5.11
In addition, direct reclaim latency is reduced by 22% at 99th
percentile and the number of refaults is reduced 7%. These metrics are important to phones and laptops as they are correlated to user experience.
>> Use cases
On Android, our most advanced simulation that generates memory pressure from realistic user behavior shows 18% fewer low-memory kills, which in turn reduces cold starts by 16%.
On Borg, a similar approach enables us to identify jobs that
underutilize their memory and downsize them considerably without compromising any of our service level indicators.
On Chrome OS, our field telemetry reports 96% fewer low-memory tab discards and 59% fewer OOM kills from fully utilized devices and no UX regressions from underutilized devices.
