perf: skip validation for default timezones by JarrodMFlesch · Pull Request #16129 · payloadcms/payload

JarrodMFlesch · 2026-04-01T18:11:21Z

Sanitizes all payload configs ~9ms faster

Payload's 48 hardcoded default timezones were being validated with new Intl.DateTimeFormat() on every cold start. This is unnecessary since they're known to be valid.

This change pre-computes a Set of default timezone values at module load and skips validation for any timezone in that set. Custom/user-provided timezones are still validated.

Before/After

Operation	Before	After
`validateTimezones`	9.06ms	0.03ms

Pre-compute a Set of default timezone values at module load time and skip Intl.DateTimeFormat validation for these known-valid values. This reduces sanitizeAdminConfig time from ~9ms to ~0.2ms by avoiding 48 unnecessary Intl.DateTimeFormat() calls on every cold start. Custom timezones (user-provided or merged with defaults) are still validated as before.

🚀 This is included in version v3.82.0

## Summary Adds lightweight profiling utilities for measuring execution time of sync and async functions. This is a developer tool for debugging performance issues during development — wrap any function with `timeSync` or `timeAsync` to measure its duration, then call `printProfileResults` to see a formatted table of timings. Not intended for production use or to be imported by default, just available when needed for performance investigations. These utilities were used to generate results for: - #16134 - #16129
