Expeditious High-Concurrency MicroVM SnapStart in Persistent Memory with an...
summary
PASS is a user-space augmented hypervisor that maps entire MicroVM snapshots into a single-tier Intel PMEM address space and implements zero-copy on-demand paging to avoid cache/DRAM copies and filesystem overhead. It is evaluated against Firecracker and FaaSnap on real workloads, showing up to 72% reduction in SnapStart latency versus Firecracker on PMEM, 47% versus FaaSnap, doubles maximum concurrency, and yields 2.2x cost-effectiveness over Firecracker.
