ThreadPilot v1.4.4

Patch release focused on reducing ThreadPilot's foreground and background runtime overhead while preserving process automation and persistent CPU-priority verification.

Measured improvements

Compared with the official v1.4.3 build on the same system and using the same Release profile:

  • Approximately 80-100% lower background idle CPU in measured tray scenarios, reaching 0% in the final idle sample.
  • Approximately 8% lower CPU overhead during process churn with 80 short-lived processes.
  • Approximately 4-5% lower hidden working-set memory.
  • Approximately 12-13% lower peak handle usage while hidden.
  • Approximately 85% fewer external command launches during visible startup, reduced from 27 to 4.

Results vary by hardware, Windows configuration, active page, and workload. The Process page remains intentionally more active while visible because it refreshes live process information.

Runtime changes

  • Cached persistent-rule snapshots in memory and pre-matched process starts before expensive enrichment.
  • Disposed process handles consistently and cleared PID-scoped caches on process exit.
  • Deferred initialization of inactive Power Plans, Rules, Settings, Tweaks, and Logs pages.
  • Reused the process monitor's initial snapshot and PID/start-time-validated static process metadata.
  • Parsed the active plan from a single powercfg /list call and limited periodic power-plan refresh to the visible Power Plans page.
  • Suspended Log Viewer collection updates while hidden and changed log flushing to one-shot scheduling.
  • Added WMI recovery backoff while preserving fallback polling reliability.

Compatibility and safety

  • Persistent rules, process start/stop tracking, and lazy diagnostics remain covered by regression tests.
  • CPU-priority verification and the bounded retry introduced for issue #32 are unchanged.
  • No default ThreadPilot affinity limit was enabled.

Validation

  • Release build completed with zero warnings and zero errors.
  • All 581 automated tests passed before release preparation.
  • CI and CodeQL passed for both performance pull requests.
  • NuGet dependency audit found no known vulnerable packages.
