+# Performance Report: 4.2.0
+
+**Generated:** 2026-01-19T01:08:20Z
+**Pipeline:** [#11105](https://git.unturf.com/engineering/unturf/un-inception/-/pipelines/11105)
+
+## Summary
+
+| Metric | Value |
+|--------|-------|
+| Total Tests | 642 |
+| Passed | 642 |
+| Failed | 0 |
+| Pass Rate | 100.0% |
+| Languages | 42 |
+| Avg Duration | 33s |
+| Slowest | raku (93s) |
+| Fastest | ocaml (19s) |
+
+---
+
+## Test Duration by Language
+
+The primary performance metric - how long each language takes to run its full test suite (15 tests per language).
+
+![Duration by Language](chart-duration-by-language.png)
+
+**Key observations:**
+- **RAKU** and **JAVASCRIPT** are outliers at 90+ seconds
+- Most languages cluster between 20-40 seconds
+- Compiled languages (red) tend to be faster than interpreted (blue)
+- **OCAML** is the fastest at 19 seconds
+
+---
+
+## Compiled vs Interpreted
+
+Comparing performance between compiled languages (C, Go, Rust, etc.) and interpreted languages (Python, Ruby, JavaScript, etc.).
+
+![Category Comparison](chart-category-comparison.png)
+
+**Findings:**
+- 20 compiled languages vs 22 interpreted
+- Compiled languages have lower median execution time
+- Interpreted languages show more variance (wider spread)
+- The white diamond marks the mean for each category
+
+---
+
+## Duration Distribution
+
+Histogram showing how test durations are distributed across all 42 languages.
+
+![Duration Histogram](chart-duration-histogram.png)
+
+**Distribution analysis:**
+- Most languages complete in 20-35 seconds (the peak)
+- Mean (green dashed) and median (blue dotted) are close together
+- Long tail on the right from slow outliers (raku, javascript)
+

+Scatter plot showing the relationship between CI queue wait time and actual test execution time.
+
+![Queue vs Execution](chart-queue-vs-execution.png)
+
+**Notes:**
+- Queue time is how long the job waited for a runner
+- Most jobs had similar queue times (clustered vertically)
+- Outliers labeled - raku and javascript took longest to execute regardless of queue time

+- **RUST** and **C** are outliers at 90+ seconds
+- Most languages cluster between 20-40 seconds
+- Compiled languages (red) tend to be faster than interpreted (blue)
+- **V** is the fastest at 40 seconds
+
+---
+
+## Compiled vs Interpreted
+
+Comparing performance between compiled languages (C, Go, Rust, etc.) and interpreted languages (Python, Ruby, JavaScript, etc.).
+
+![Category Comparison](chart-category-comparison.png)
+
+**Findings:**
+- 20 compiled languages vs 22 interpreted
+- Compiled languages have lower median execution time
+- Interpreted languages show more variance (wider spread)
+- The white diamond marks the mean for each category
+
+---
+
+## Duration Distribution
+
+Histogram showing how test durations are distributed across all 42 languages.
+
+![Duration Histogram](chart-duration-histogram.png)
+
+**Distribution analysis:**
+- Most languages complete in 20-35 seconds (the peak)
+- Mean (green dashed) and median (blue dotted) are close together
+- Long tail on the right from slow outliers (rust, c)
+
+---
+
+## Speed Leaders
+
+Side-by-side comparison of the 10 slowest and 10 fastest languages.
+
+![Speed Leaders](chart-speed-leaders.png)
+
+**Slowest (left):** RUST, C, PYTHON, TYPESCRIPT, JAVASCRIPT
+**Fastest (right):** V, D, KOTLIN, AWK, RAKU
+
+---
+
+## Queue vs Execution Time
+
+Scatter plot showing the relationship between CI queue wait time and actual test execution time.
+
+![Queue vs Execution](chart-queue-vs-execution.png)
+
+**Notes:**
+- Queue time is how long the job waited for a runner
+- Most jobs had similar queue times (clustered vertically)
+- Outliers labeled - rust and c took longest to execute regardless of queue time

+# Performance Report: 4.2.4
+
+**Generated:** 2026-01-19T12:02:14Z
+**Pipeline:** [#11256](https://git.unturf.com/engineering/unturf/un-inception/-/pipelines/11256)
+
+## Summary
+
+| Metric | Value |
+|--------|-------|
+| Total Tests | 682 |
+| Passed | 682 |
+| Failed | 0 |
+| Pass Rate | 100.0% |
+| Languages | 42 |
+| Avg Duration | 70s |
+| Slowest | python (110s) |
+| Fastest | c (23s) |
+
+---
+
+## Test Duration by Language
+
+The primary performance metric - how long each language takes to run its full test suite (15 tests per language).
+
+![Duration by Language](chart-duration-by-language.png)
+
+**Key observations:**
+- **PYTHON** and **JAVASCRIPT** are outliers at 90+ seconds
+- Most languages cluster between 20-40 seconds
+- Compiled languages (red) tend to be faster than interpreted (blue)
+- **C** is the fastest at 23 seconds
+
+---
+
+## Compiled vs Interpreted
+
+Comparing performance between compiled languages (C, Go, Rust, etc.) and interpreted languages (Python, Ruby, JavaScript, etc.).
+
+![Category Comparison](chart-category-comparison.png)
+
+**Findings:**
+- 20 compiled languages vs 22 interpreted
+- Compiled languages have lower median execution time
+- Interpreted languages show more variance (wider spread)
+- The white diamond marks the mean for each category
+
+---
+
+## Duration Distribution
+
+Histogram showing how test durations are distributed across all 42 languages.
+
+![Duration Histogram](chart-duration-histogram.png)
+
+**Distribution analysis:**
+- Most languages complete in 20-35 seconds (the peak)
+- Mean (green dashed) and median (blue dotted) are close together
+- Long tail on the right from slow outliers (python, javascript)
+
+---
+
+## Speed Leaders
+
+Side-by-side comparison of the 10 slowest and 10 fastest languages.
+
+![Speed Leaders](chart-speed-leaders.png)
+
+**Slowest (left):** PYTHON, JAVASCRIPT, ELIXIR, SCHEME, BASH
+**Fastest (right):** C, D, COBOL, RAKU, CPP
+
+---
+
+## Queue vs Execution Time
+
+Scatter plot showing the relationship between CI queue wait time and actual test execution time.
+
+![Queue vs Execution](chart-queue-vs-execution.png)
+
+**Notes:**
+- Queue time is how long the job waited for a runner
+- Most jobs had similar queue times (clustered vertically)
+- Outliers labeled - python and javascript took longest to execute regardless of queue time
+

+# Performance Report: 4.2.5
+
+**Generated:** 2026-01-19T19:10:23Z
+**Pipeline:** [#11336](https://git.unturf.com/engineering/unturf/un-inception/-/pipelines/11336)
+
+## Summary
+
+| Metric | Value |
+|--------|-------|
+| Total Tests | 658 |
+| Passed | 658 |
+| Failed | 0 |
+| Pass Rate | 100.0% |
+| Languages | 42 |
+| Avg Duration | 67s |
+| Slowest | v (114s) |
+| Fastest | erlang (44s) |
+
+---
+
+## Test Duration by Language
+
+The primary performance metric - how long each language takes to run its full test suite (15 tests per language).
+
+![Duration by Language](chart-duration-by-language.png)
+
+**Key observations:**
+- **V** and **HASKELL** are outliers at 90+ seconds
+- Most languages cluster between 20-40 seconds
+- Compiled languages (red) tend to be faster than interpreted (blue)
+- **ERLANG** is the fastest at 44 seconds
+
+---
+
+## Compiled vs Interpreted
+
+Comparing performance between compiled languages (C, Go, Rust, etc.) and interpreted languages (Python, Ruby, JavaScript, etc.).
+
+![Category Comparison](chart-category-comparison.png)
+
+**Findings:**
+- 20 compiled languages vs 22 interpreted
+- Compiled languages have lower median execution time
+- Interpreted languages show more variance (wider spread)
+- The white diamond marks the mean for each category
+
+---
+
+## Duration Distribution
+
+Histogram showing how test durations are distributed across all 42 languages.
+
+![Duration Histogram](chart-duration-histogram.png)
+
+**Distribution analysis:**
+- Most languages complete in 20-35 seconds (the peak)
+- Mean (green dashed) and median (blue dotted) are close together
+- Long tail on the right from slow outliers (v, haskell)
+
+---
+
+## Speed Leaders
+
+Side-by-side comparison of the 10 slowest and 10 fastest languages.
+
+![Speed Leaders](chart-speed-leaders.png)
+
+**Slowest (left):** V, HASKELL, SCHEME, OCAML, POWERSHELL
+**Fastest (right):** ERLANG, AWK, BASH, DENO, TCL
+
+---
+
+## Queue vs Execution Time
+
+Scatter plot showing the relationship between CI queue wait time and actual test execution time.
+
+![Queue vs Execution](chart-queue-vs-execution.png)
+
+**Notes:**
+- Queue time is how long the job waited for a runner
+- Most jobs had similar queue times (clustered vertically)
+- Outliers labeled - v and haskell took longest to execute regardless of queue time
+

+
+## Dashboard
+
+Summary dashboard combining key metrics and visualizations.

+# Performance Report: 4.2.6
+
+**Generated:** 2026-01-19T20:22:16Z
+**Pipeline:** [#11363](https://git.unturf.com/engineering/unturf/un-inception/-/pipelines/11363)
+
+## Summary
+
+| Metric | Value |
+|--------|-------|
+| Total Tests | 642 |
+| Passed | 642 |
+| Failed | 0 |
+| Pass Rate | 100.0% |
+| Languages | 42 |
+| Avg Duration | 54s |
+| Slowest | haskell (128s) |
+| Fastest | awk (23s) |
+
+---
+
+## Test Duration by Language
+
+The primary performance metric - how long each language takes to run its full test suite (15 tests per language).
+
+![Duration by Language](chart-duration-by-language.png)
+
+**Key observations:**
+- **HASKELL** and **GO** are outliers at 90+ seconds
+- Most languages cluster between 20-40 seconds
+- Compiled languages (red) tend to be faster than interpreted (blue)
+- **AWK** is the fastest at 23 seconds
+
+---
+
+## Compiled vs Interpreted
+
+Comparing performance between compiled languages (C, Go, Rust, etc.) and interpreted languages (Python, Ruby, JavaScript, etc.).
+
+![Category Comparison](chart-category-comparison.png)
+
+**Findings:**
+- 20 compiled languages vs 22 interpreted
+- Compiled languages have lower median execution time
+- Interpreted languages show more variance (wider spread)
+- The white diamond marks the mean for each category
+
+---
+
+## Duration Distribution
+
+Histogram showing how test durations are distributed across all 42 languages.
+
+![Duration Histogram](chart-duration-histogram.png)
+
+**Distribution analysis:**
+- Most languages complete in 20-35 seconds (the peak)
+- Mean (green dashed) and median (blue dotted) are close together
+- Long tail on the right from slow outliers (haskell, go)
+
+---
+
+## Speed Leaders
+
+Side-by-side comparison of the 10 slowest and 10 fastest languages.
+
+![Speed Leaders](chart-speed-leaders.png)
+
+**Slowest (left):** HASKELL, GO, CPP, RUST, FORTH
+**Fastest (right):** AWK, POWERSHELL, CRYSTAL, RAKU, DENO
+
+---
+
+## Queue vs Execution Time
+
+Scatter plot showing the relationship between CI queue wait time and actual test execution time.
+
+![Queue vs Execution](chart-queue-vs-execution.png)
+
+**Notes:**
+- Queue time is how long the job waited for a runner
+- Most jobs had similar queue times (clustered vertically)
+- Outliers labeled - haskell and go took longest to execute regardless of queue time
