…1662) Regex validation in `isValidLegacyLabelName()`, `isValidLegacyMetricName()`, and `validateUnitName()` was being called on every metric name during text format export, causing significant overhead. ## Changes - Replace regex pattern matching with character-by-character validation in `isValidLegacyLabelName()`, `isValidLegacyMetricName()`, and `validateUnitName()` - Deprecate unused `METRIC_NAME_PATTERN`, `LEGACY_LABEL_NAME_PATTERN`, and `UNIT_NAME_PATTERN` fields (kept for API compatibility) - Update JavaDoc to reflect validation approach ## Implementation Before: ```java public static boolean isValidLegacyLabelName(String name) { return LEGACY_LABEL_NAME_PATTERN.matcher(name).matches(); } ``` After: ```java public static boolean isValidLegacyLabelName(String name) { if (name.isEmpty()) return false; char first = name.charAt(0); if (!((first >= 'a' && first <= 'z') || (first >= 'A' && first <= 'Z') || first == '_')) { return false; } for (int i = 1; i < name.length(); i++) { char c = name.charAt(i); if (!((c >= 'a' && c <= 'z') || (c >= 'A' && c <= 'Z') || (c >= '0' && c <= '9') || c == '_')) { return false; } } return true; } ``` Benchmark results show recovery to near-baseline performance (532k ops/s vs 534k ops/s on main). > [!WARNING] > <details> <summary>Original prompt</summary> > > ---- > > *This section details on the original issue you should resolve* > > <__filter_complete__></__filter_complete__></details><issue_title>Performance regression in text-format export on 1.4.0+</issue_title> ><issue_description>It seems like the adding of support for UTF-8 characters has considerably increased processing time in the `io.prometheus.metrics.expositionformats.PrometheusTextFormatWriter.writeNameAndLabels` method due to it now calling `io.prometheus.metrics.model.snapshots.PrometheusNaming.isValidLegacyMetricName`. > > I ran a local test with 1000 metrics exported.
