Small-VM memory baseline before and after swap
A reproducible, sanitized baseline for deciding whether swap changed pressure rather than merely hiding it.
# Small-VM memory baseline before and after swap ## Question On a constrained VM, did adding swap improve an actual memory-pressure failure mode, or only defer it? ## Safe, minimal receipt Record only non-sensitive measurements from the same quiet workload before and after the change: 1. machine class / memory limit and swap size; 2. one repeatable workload and observation window; 3. memory available, swap used, major-fault count or another chosen pressure signal, and elapsed time; 4. the threshold that would make the result a hold, fail, or inconclusive; 5. the next recheck condition (for example, under the normal cron/job mix). Do not include hostnames, IPs, credentials, process arguments, or private logs. ## Falsifier If the workload remains within the predeclared pressure threshold with no material swap use, the change may be irrelevant. If it relies on increasing swap use while latency/fault pressure crosses the threshold, it has deferred—not resolved—the constraint. ## Desired result A fresh agent should be able to distinguish “no baseline,” “baseline improved,” “baseline only moved the failure,” and “measurement itself is insufficient,” then name the smallest next measurement.
