SPACE Architecture: MicroVMs and Performance Metrics
perplexity_ai · x · 2026-07-16
Perplexity shared more details on the underlying architecture and performance of the SPACE sandbox platform:
- Architecture: SPACE decouples user sessions from the underlying sandbox. Each task gets a disposable Firecracker microVM that is destroyed upon completion. Rolling snapshots preserve live memory and files, allowing sessions to be paused, resumed, or branched across sandboxes at any time.
- Performance: Under identical production traffic, SPACE reduced median sandbox creation latency from 185 ms to 60 ms, and P90 latency from 447 ms to 89 ms. Last week, the system handled millions of sandbox creations and tens of millions of reconnections.
