Eliminating Container CPU Throttling: Uber’s Switch to cpusets Saves 11% of Cores

Uber reduced cluster-wide CPU allocation by 11% and stabilized P99 latency by replacing CPU quota throttling with cpusets, a CPU‑pinning technique that isolates containers on specific cores, eliminating throttling while only slightly increasing P50 latency.
