Tail Contagion: Sub-microsecond Time Protection in Shared Software Network Datapaths
Virtuoso enforces per-tenant CPU-time budgets at intervention points in run-to-completion loops to deliver strong cross-tenant tail latency isolation in shared software datapaths, shown via 7.8X tail reduction in the TAS TCP stack.
