Sabre: Hardware-Accelerated Snapshot Compression for Serverless MicroVMs
Talkat 18th USENIX Symposium on Operating Systems Design and Implementation (OSDI '24) · 2024-07-10..07-12·
summary
Presents a system that uses a near‑memory IA accelerator to do lossless page (de)compression and zero‑copy prefetching for Firecracker microVMs, building a library that maps snapshot partitions through the page request service and DMAs decompressed pages into guest memory. Demonstrates up to 4.5× compression on real serverless snapshots, 55% prefetch speedup and up to 20% end‑to‑end cold‑start reduction, with decompression latency hidden behind I/O and page‑fault handling.
