- Curtsinger and Berger's SOSP 2015 paper explores optimization opportunities by virtually speeding up selected code through pauses in other threads, then measuring progress. A useful qualification: section 4.1 evaluates throughput, not latency; section 4.3 directly compares quantified local changes with predictions for ferret and dedup. Those author case studies should not be read as independent validation for arbitrary code changes.
